How to convert Moles of a substance to grams? Moles to grams in a substance or compound?
Practice questions/worksheet on moles to grams
Use the following formula to calculate Moles to grams.
Mole(n)= Mass of a substance(m)/ Molar mass(Mr)
so mass of a substance , m= nx Mr
The first question is solved for you.
For calculating Molar mass, you need to add the relative atomic masses of all the atoms in a
compound or ion. For example Mr of Na2O = (23×2)+16 = 62 ,
because Ar( relative atomic mass) of Na=23,
Ar( relative atomic mass) of O= 16
so mass of 1.5 moles of Na2O= 1.5×62= 93 g
