Stoichiometry Molar Mass The trick: By definition, this is the mass ofmol of a substance (i.e., g/mol) – The molar mass of an element is the mass number for the element that we find on the periodic table – The formula weight (in amuʼs) will be the same number as the molar mass (in g/mol) This document contains past exam Stoichiometry WorkSheetWorked Solutions Answer the following questions on your own paper.
