Previous question Next question. This is how to calculate molar mass (average molecular weight), which is based on isotropically weighted averages. )-, (? 0 0 493; Anonymous. Total: 206 g/mol of ibuprofen Find the molar mass of Ibuprofen. 156+18+32=(206) for the purpose of the example we are using 206.31 as molar mass because it is 100% accurate and not a rounded representation of the atomic mass of the other elements. Molecular weight is actually an older term of “relative molar mass” or “molecular mass”, which is a dimensionless quantity equal to the molar mass divided by the molar mass constant defined by 1 g/mol.
