## Question:

How much potassium chloride in grams is needed to prepare {eq}1500\ ml {/eq} solution of {eq}\rm 3\ M\ KCl {/eq} solution?

## Molarity:

A quantitative method to express the concentration of a solution is by the use of molarity. The molarity of a solution is defined as the moles of solute per liter of solution.

{eq}Molarity~=~\frac{mol~solute}{liter~solution} {/eq}
