•OBJECTIVE: Students will use the mole to determine the mass in a specified amount of matter by completing examples in their note books.

•W.O.D. Mimic-to imitate, to copy

•WARM-UP

Using the 5 samples on the lab bench, record the chemical formula & mass of 1 mole of each sample.

1.If each sample represents 1 mole, why are the masses (amount of sample) different?

2.How many representative particles are there in each sample?
