Objective 1

I know what a mole is and I can express the number of particles in mole.

Objective 2

I know what molar mass is and I can determine it for both elements and

compounds.

Objective 3

I know the counting-by-weighing method and can use it to do mass-mole

conversions.

Objective 4

I know how to calculate mass percent from experimental data or from

chemical formulas.

Objectives 5, 6, and 7

I know the difference between empirical and molecular formulas. I know how to

determine the empirical formula from mass data or from mass percent data. I

know how to determine the molecular formula from an empirical formula and

the molar mass.
