Answer
12.01 grams per mole
Work Step by Step
To find the molar mass of a compound:
Use the chemical formula to determine the number of each type of atom present in the compound.
Multiply the atomic weight (from the periodic table) of each element by the number of atoms of that element present in the compound.
Remember — that's the number written under the element symbol and element name. For example, take a look at carbon and you'll see it has an atomic mass of 12.01. So the molar mass of carbon is 12.01 grams per mole.
