Question

What is the molarity of a solution containing 5.0 moles of solute dissolved in enough water to make 250 milliliters of solution?

Answer 1

Explanation:

1 Answer. The molarity of the solution is 5.1 mol/L

Answer 2

Answer:

The molarity of the solution is

5.1 mol/L

.

The solution is said to be

5.1 molar

.

The shorthand way to indicate molarity is

5.1 M

, which is pronounced

5.1 molar

, and is how it is written on the label of its container.

Explanation:

Molarity (M)

=

moles of solute

liters of solution

The volume of the solution is given in mL. The volume is required to be in liters, so

975 mL

must be converted to liters.
