Chemistry Conversions Exam Questions Correctly Answered. Converting moles to grams - CORRECT ANSWER There are three steps to converting moles of a substance to grams: Determine how many moles are given in the problem. Calculate the molar mass of the substance. Multiply step one by step two. Converting grams to moles - CORRECT ANSWER Using a calculator, divide the number of grams by the molar mass. The result is the number of moles in your element or compound. For example, imagine you ...
