1. The problem statement, all variables and given/known data Glacial acetic acid has a density of 1.05g/ml and contains 99.51%acetic acid (CH3COOH) by mass. Calculate the molarity of glacial acetic acid. So, this is a question in my pre-lab that doesn't even count. But, I still want to get it because we have similar questions in exams. I'm blocked at the first step: What is molarity? Is is the total number of moles? or just the number of acetic acid moles?
