Calculate the molarity of a solution prepared by dissolving 89 g of KNO₃ in 0.525 L of water. Show your work.

2 answers

0.525 L of water, so assume this is the volume of the solution
Molarity= (89/formulamassKNO3) /.525 L solution
so figure the formula mass of potassium nitrate.
well, how many grams of KNO3 in a whole liter?
89 / 0.525 = ?
then how many mols is that ?
well 1 mol = 39 + 14 + 3*16 = 101 grams / 1 mol
so
? grams * 1 mol/101 grams
