You dissolve 0.74 g of potassium chloride (kcl) in 500 ml of water. what is the molarity of the 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. The concentration of the solution is calculated as follows: 

Molarity = 0.74 g (1 mol / 74. 55 g) / 500mL (1 L / 1000 mL)

Molarity = 0.02 M

0.O2M

Explanation: Took the Test it is correct :)
