Calculations should be organized so the reader can follow what you are solving for -- in other words
test worthy work is always required.
If you are using an equation, write the equation (if necessary, rearranged so the variable you are solving for is on the left hand side) and include all units throughout your calculations--this is so the final units match to the units you would expect.
d= m
V
= 24.40 g
20.3mL
= 1.20 g/mL (round to the proper # of sig figs)
If you are using dimensional analysis, include labels and units with all the numbers.
Don't forget to follow the rules for significant figures for +/- and x/÷. This is especially important for the measurements you are taking. You can not calculate values that go beyond the precision of your equipment.
Also, remember that while you may work together with other students, make sure you use your data and punch the numbers into your calculator. Identical calculator errors are a sign of plagiarism. Plagiarism is serious. It is your job to make sure that your work is your own.
Graphs should be done in Logger Pro or on a spread sheet unless otherwise stated.
