Then, calculate the molarity of a solution made by adding 5.57 g of cacl2 to enough water to create a solution with a total volume of 2.50 l. enter only a numerical value in the correct number of significant figures.

The answer to your question is: 0.02 M

Explanation:

Data

mass = 5.57 g

volume = 2.50 L

Formula

Molarity =

Process

1.- Calculate the molecular mass of CaCl₂

Molecular mass 0f CaCl₂ = 40 + (35.5 x 2) = 111 g

2.- Calculate the moles of CaCl₂ in 5.57 g

                                111 g of CaCl₂  ---------------- 1 mol

                                 5.57 g of CaCl₂ -------------   x

                                   x = (5.57 x 1) / 111

                                   x = 0.050 moles of CaCl₂

3.- Calculate molarity

      Molarity = 0.02
