First, we assume 1000 grams of solvent. This means there are 3.97 moles of sulfuric acid. This is equal to 389.06 grams acid. The total mass of the solution is 1389.06 grams. Using density, the number of liters is 1.142 liters. The molarity in this case is equal to 3.475 molar
(150 grams)(45/100)=(x)(85.5/100)
67.5=.855(x)
x=78.947368 grams of stock solution
