Molar mass nitrogen ( N2 ) = 28.02 g/mol. 1 mol N2 -------> 28.02 g. 4.60 mol ---------> x g. x = 4.60 * 28.02. x = 129 g of N2. hope this helps!.
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.
