mol of CaSO4 has mass of 136 grams
https://answers.yahoo.com/question/index?qid=20100111143339AAYHMMI
so you have
157/136 mols in 7.24*10^2 * 10^-3 liter
so
(157/136)mols / 0.724 liters = the mols per liter
When 157 grams of caso4 are dissolved in enough water to yield a volume of 7.24×10^2 milliliter of solution the molarity of the solution will be?
