The formula mass formula weight of a molecule is the sum of the atomic weights of the atoms in its empirical formula. Molar mass is the mass in grams of 1 mol of substance The number of particles in a mole is equal to 6022 10 23. So if i write C O2 CO2 the weights of atoms on both sides here are 44.
Molecular weight is the collection of weights of all the atoms in a molecular formula.
Formula mass represents the mass of the total reagents as written in the formula. In practice C exists as an amorphous mass rather than individual molecules of C or C2 or whatever. Note here that it supposes that C exists at free atoms like He. But this quantity is in the unified mass unit u.
