Potassium fluoride is used for frosting glass. calculate the molarity of a solution prepared by dissolving 78.6 g of kf in enough water to produce 225 ml of solution.

There are a number of ways to express concentration of a solution. This includes molarity. Molarity is expressed as the number of moles of solute per volume of the solution. We calculate as follows:

Molarity =  78.6 g KF ( 1 mol / 58.1 g ) / .225 L = 6.013 mol / L KF solution
