WebSo molarity, let's start there, is really talking about moles of something, some particle, over 1 liter of solution. And I haven't been writing out liter of solution, but that is what is meant, … WebWe can calculate the number of moles of acetic acid as its mass divided by its molar mass. moles CH 3CO 2H = 3.78 gCH 3CO 2H 60.05g / mol = 0.0629 mol. The volume of the solution equals its mass divided by its density. volume = mass density = 100.0 g solution 1.00 g / mL = 100 mL. Then calculate the molarity directly.
