___________________ is a MOLE MASTER!
Date: _____________________
Unit Six: The Mole
SC2c: Apply concepts of the mole and Avogadro’s number to conceptualize and
calculate mass, moles, and molecules relationships, and molar volumes of
gases.
Directions – Choose three calculations to complete. You must win “THINK tac
toe” & pass through the center block. Be sure to show all of your work on a
separate sheet of paper.
1. Calculate the number
of grams of iron that
contain the same number
of atoms as 2.24 g of
cobalt.
2. Calculate the number
of moles present in 151
kg of iron. How many
atoms of iron are
present?
3. The molar mass of
sodium acetate is
_____________.
4. The molar mass of
ammonium sulfate is
___________________.
5. Consider a 20.0 g
sample of Ag and a 20.0
g sample of another
“mystery” metal. You are
told that there are exactly
four times as many
atoms of the “mystery”
metal as of silver metal.
Identify the “mystery”
metal.
6. Calculate the mass in
grams of 1.50 moles
aluminum iodide. How
many formula units are
present?
7. Calculate the number
of molecules present in
6.37 g of carbon
monoxide. What volume
will the gas need to be
contained?
8. The molar mass of
sodium thiosulfate
(Na2S2O3) is
_________________.
9. The molar mass of
calcium nitrate is
_____________.
