Oct 07, 2007· A 1.50 M ammonium sulfate solution has 1.50 moles of ammonium sulfate per 1 Liter of solution. The molar mass of ammonium sulfate is 132.19 g/mol, so 1.50 moles of ammonium sulfate is: 1.50 mol x (132.19 g)/(1 mol) = 198 grams. So in order to prepare 1 liter of a 1.50 M ammonium sulfate solution, you need 198 grams.
