22) Calculate the molarity of a sugar solution if 4 liters of the solution contains 12 moles of sugar.

[]Sugar] = 3M

Explanation:

Molarity indicates the moles of solute that are contained in 1 L of solution.

For this case, solute is the sugar

And the volume of solution is 4L

Molarity (mol/L) → 12 mol/4L = 3M

We can also make a rule of three to determine this:

4 liters of solution have 12 moles of solute (sugar)

1 liter of solution must have (1. 12) / 4 = 3 moles
