What is the molarity of a solution that contains 612 grams of cacl2 in 3.04 liters of solution?

1.81 m
201 m
5.52 m

1.       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 = 612 g (1 mol / 110.96 g) / 3.04 L

Molarity = 1.81 M

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .
