After unzipping the zoluto # .zip file (where # is the version number of the program), it is convenient to save the folder and its contents in an appropriate place on your computer and create a shortcut of the zoluto # .jar file to be run from the desktop.

Run directly (double-click on the left mouse button) the file "zoluto # .jar" (or its shortcut), this should be enough to run the program.

If the program does not start and / or a folder is opened with the contents of the program codes, two things may be happening:

1) - You do NOT have java installed on your computer.

Follow the instructions below:

To run this program properly, you must have Java SE Runtime Environment (JRE) installed on your computer.

In most cases this program is already installed. If not, it can be downloaded from the official ORACLE website (in English):

http://www.oracle.com/

or

http://www.oracle.com/technetwork/java/javase/downloads/jre-7u3-download-1501631.html

Follow the instructions for your operating system.

After the installation is finished, try to start the application again.

2) -java IS installed on your computer, but the extension “.JAR” is not associated with it.

In most systems this is solved by clicking on the right button of the mouse and selecting the option "Open With", this will display a list of possible applications to open this file. Must be selected: java (TM) Platform binari (for windows) or Sun java Runtime (for linux-Ubuntu)

Select the appropriate program and check the box that tells the system that from now on this program will always be used to open these kinds of files

If these programs do not appear in the list, select the "Search" option. In the case of computers with Windows system, the program should be stored in the "Program Files" folder.

The program handles the following data inputs:

Compound: Name of the compound.

Solvent: Solvent name

Note: These fields are optional, but their use is recommended in order to make the presentation of the results clearer to understand.

Molecular weight: molecular weight of the compound studied. Unit grams / mole.

Moles: Moles of the compound studied. Units: Molar, mMplar, µMolar and nMolar.

Mass: Mass of the compound studied. Units: kilograms, grams, mgrams, µgrams.

Initial Volume: Volume of a stock solution before diluting. Units: Liters, mLiters, µLiters.

Final Volume: Final volume of the solution to be prepared. Units: Liters, mLiters, µLiters.

Initial Concentration: Concentration of the stock solution. Units: Molar, mMolar, µMolar, grams / Liter, mg / Liter.

Final Concentration: Final concentration of the solution to be prepared. Units: mMolar, µMolar, grams / Liter, mg / Liter.

Note: These data may or may not be mandatory depending on the type of calculation to be performed.

The text box where the nominal value of each data is written, only accepts numbers and commas in the format "#, #", example "2.34".

Note: In systems where the language is "English" the comma will be replaced by a period (".") According to the format "#. # Example 2.34. This is because the program detects the language of the system and adapts it according to the use of each region.

Once the nominal value of the data entry has been indicated, the unit of each one is indicated by selecting it from a drop-down list immediately to the right of the text box.

Example.

Compound: Na-Chloride

Molecular Weight: 58,443

Solvent: Solvent

Initial Concentration: 150 mM.

Final Concentration: 5 Molar.

The first thing to do is select the type of calculation you want to perform, from a list to the right of the "calculate" button.

To select

Convert unit

Moles / Mass / Initial Volume

Final Volume

Final Concentration

Note: When choosing each of the options, you will notice that the data fields that are not necessary for the chosen type of calculations are invalidated. This is so that only the data that is relevant is inserted.

After entering the data, press the "calculate" button and the result will appear in the "Result" text field.

Convert between Molar and gram / Liter. For this calculation it is always necessary to know the molecular weight of the compound.

Real life example: I have a 5 Molar NaCl solution and I want to know what its concentration is in grams / liter.

a) Select type of calculation> Convert Unit

b) Fill in the data entries.

Compound: NaCl

Solvent: water

Molecular Weight: 58.44 (mandatory)

Final Concentration: 5 Molar.

c) Press the "Calculate" button

The purpose of this calculation is to know what the mass of solid drug will be, its moles and / or the initial volume of a stock solution, which will be necessary to prepare a solution whose final concentration and final volume are determined.

Real life example: I have a 5 Molar NaCl solution and I want to prepare 500 mL of 150 mMolar NaCl

a) Select type of calculation> Moles / Mass / Initial Volume

b) Fill in the data entries.

Compound: NaCl

Solvent: water

Molecular Weight: 58.44 (optional in this case)

Initial Concentration: 5 Molar.

Final Concentration: 150 mMolar

Final Volume: 500 mLiter

c) Press the "Calculate" button

The purpose of this calculation is to know what will be the final volume of a solution that has a determined final concentration, when a mass of compound (or its moles) or a stock solution of known volume and concentration is available.

Real life example: I have 34.0 grams of NaCl of Molecular Weight 58.43 g / mol and I want to prepare a 1 Molar solution of NaCl

a) Select type of calculation> Final Volume

b) Fill in the data entries.

Compound: NaCl

Solvent: water

Molecular Weight: 58.44

Final Concentration: 1 Molar

c) Press the "Calculate" button.

The purpose of this calculation is to know what the Final Concentration of a solution with a determined final volume will be, when the mass of compound (or its moles) or a stock solution of known volume and concentration is available.

Real life example: I have 34.0 grams of NaCl of Molecular Weight 58.43 g / mol and I want to know what the concentration of the solution will be if I dissolve it in 500 ml of water.

a) Select type of calculation> Final Concentration

b) Fill in the data entries.

Compound: NaCl

Solvent: water

Molecular Weight: 58.44 (mandatory in this case)

Final Volume: 500 mL

c) Press the "Calculate" button

Write the name of the desired compound in the text field "Compound"

Write the molecular weight value of the compound in the "Molecular Weight" text field.

Alternatively, go to the menu bar and select

Edit> Delete Compound.

A list of compounds (file type "list_name.lst") can be exported or imported in order to save it in a safe place in case of data loss or to share it with other users.
