In this lab you will investigate the relationship between the density and concentration of a solution. You will prepare a stock solution of sucrose (table sugar), make 4 diluted solutions of different concentrations, construct a calibration curve of your data, and use that curve and the density of an unknown sucrose solution to determine the concentration.

Making solutions is a crucial skill for a chemist. Watch the video to review the proper technique for making solutions. You are permitted to use up to 20 g of sucrose to make 100.00 mL of stock solution.

As with the previous lab, you will dilute your stock solution multiple times to create a series of aqueous sucrose solutions with a variety of concentrations. Unlike the last lab, you will not be assigned specific dilutions to perform, you must choose them yourself.

Once you have determined the density for the solutions of known concentrations, you will be assigned a solution with an unknown concentration of sucrose to work with. Look back at the food dye analysis lab if you're unsure how to determine the concentration of sucrose in the unknown solution.

At the conclusion of the lab, the actual values of the unknown sucrose solutions will be posted. Evaluate the quality of your data using percent error.
