Solution: 12/6.022*10^23 = 1.9927*10^-23. We know that carbon 12 has a mass of 12 a.m.u and 1 amu =1.66*10^-24 grams.
Molar Mass is how much one mole weighs of a particular compound. You can have a mole of hydrogen and a mole of helium but the mole of helium is going to way twice as much because a hydrogen has 1 proton+neutron whereas the helium has 2 proton+neutron pairs. The AMU is a unit of mass measurement on the atomic scale. 1 mole of 1 AMU weights out to 1 gram. By knowing the AMU of an atom or compound you automatically know its molar mass.
