What is the number of moles of a solute that is dissolved in 1 L of solution?

A. mass percent

B. molality

C. molarity

D. mole fraction

Molarity

Explanation:

We need to know the definition of molarity;

What is molarity?

Molarity is the concentration of a solution in moles per liter.

How is molarity calculated?

Molarity is calculated by dividing the amount of solute in moles by the volume of solution in liters.

Example;

If a 0.25 moles of Sodium hydroxide are dissolved in 500 mL of solution. Then molarity will be;

Molarity = Moles : Volume

= 0.25 moles : 0.5 L

= 0.5 Mol/L

Therefore, the molarity of sodium hydroxide solution will be 0.5 mol/L.
