What is the molarity of a solution containing 11.2 g ca(no3)2 in 175 ml of solution? what is the molarity of a solution containing 11.2 in 175 of solution? 1.96×103 m 64.0 m 0.063 m 0.390 m

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 do as follows:

11.2 g Ca(NO3)2 in 175 mL of solution

Molarity = 11.2 g Ca (NO3)2 (1 mol / 164.09) / .175 L solution
Molarity = 0.390 M

The correct answer is b) false
