The molarity of a solution with 55 grams of CaCl2 dissolved in 0.78 L is 0.64M. Details about molarity is found below.

How to calculate molarity?

The molarity of a solution can be calculated by dividing the number of moles of the substance by its volume.

However, the number of moles of a substance must first be calculated using the following expression:

no of moles = 55g ÷ 111g/mol

no of moles = 0.49mol

Molarity of CaCl2 solution = 0.49mol ÷ 0.78L

Molarity of CaCl2 solution = 0.64M

Therefore, the molarity of a solution with 55 grams of CaCl2 dissolved in 0.78 L is 0.64M.
