If the molecular weight of a protein is given as 90,000 are the units g/mol or simply g? I have seen mixed answers to this question.

It will be 90,000 g/mol since 1 mol will have a mass of 90,000. But many simply drop the the mol and say the molecular weight is 90,000 g and we all understand it is the mass of mol (hence the term "molecular weight" which has been replace in recent years as "molar mass."
