An aqueous KNO3 solution is made using 73.4g of KNO3 diluted to a total solution volume of 1.86 L. Calculate the molarity of the solution. (Assume a density of 1.05 g/ml for the solution.)

You do not need the density to solve since the total volume is given
Molarity=moles/liters
73.4g of KNO3/101.1032 g of KNO3/mol= moles of KNO3
Molarity=moles/liters=moles of KNO3/1.86L
