Molar mass is the mass of
one mole of a substance, it can be a chemical element or a compound. It is a
characteristic of each pure substance. We calculate it by adding up all of the masses of the atoms involved in the compound. We calculate as follows:
atomic mass total mass
C 17 12.01 g/mol 204.17 g/mol
H 19 1.01 g/mol 19.19 g/mol
N 1 14.00 g/mol 14.00 g/mol
O 3 16.00 g/mol 48.00 g/mol
------------------------------------------------------------
Molar mass = 285.36 g/mol
What is the mass of 6.02 x 10^24 molecules of morphine?
6.02 x 10^24 molecules ( 1 mol / 6.02x10^23 molecules) ( 285.36 g/mol) = 2853.6 g morphine
