1. According to the diagram, what three quantities can you calculate if you know the
number of moles of a compound?
2. According to the diagram, what three quantities can you calculate from a mass
measurement of a compound?
3. If you were given the number of moles of a compound, what quantity would you need to
know to calculate the mass of that number of moles of the compound?
4. If you were given the number of moles of a compound, what information would you
need to know to determine each of the conversion factors necessary to find the number of
moles of each atom or ion in the compound?
5. You are given a 2.0-mol sample of calcium carbonate (CaCO3). The molar mass of
CaCO3 is 100.09 g/mol. Write the conversion factor you would use to determine
correctly each of the following quantities.
a. the mass in grams of the sample
b. the number of formula units of CaCO3 in the sample
c. the number of moles of oxygen atoms in the sample
6. Write the conversion factors in the order you would use them to determine correctly each
of the following quantities in a sample of 2.0 3 1024 molecules of ethane (C2H6). The
molar mass of ethane is 30.08 g/mol.
a. the mass in grams of the sample
b. the number of carbon atoms in the sample
