Activity 3: Percent Composition of NIPS
Objectives:
After performing this activity, you should be able to:
1. Determine the molar mass of a compound;
2. Solve the percentage composition of a compound.
Materials: Package of Nips
Procedure:
1. Obtain a package of NIPS® and count the number of each color in
your pack. Enter in data table.
2. Determine the total masses for each color for the compound. (so if you have 3 atoms of green
times the molar mass given which is 7g the total mass would be 21g).
3.Use the formula for % composition to determine the percentage composition of each “atom”
(color) in the compound (candy pack).
