Molar Mass
The mass of 1 mole of an element or compound
Units: g (grams)
Molar mass = atomic mass
Atomic mass of each element is in RED (units are amu)
Round to the nearest hundredth!!

For an Element
Take the element Carbon (C) Molar mass = 12.01g 1 mol of C = 12.01g
How about Boron (B)? Molar mass =

For a Compound
Take the compound NO Molar mass of the compound = sum of the molar
mass of each element 14.01 + 16.00 = 30.01g 1 mole of NO = 30.01g
How about CO2
Molar mass =
