Then, calculate the molarity of a solution made by adding 5.3 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. use the periodic table that is part of your exam to calculate molar mass. do not enter units in the answer box, but know that the symbol for the unit of this calculation is m.

The answer to your question is:  0.02

Explanation:

Data

Mass = 5.3 g of CaCl₂

Volume = 2.5 l

Molarity = ?

Formula

Molarity =

Process

1.- Calculate the molecular mass of CaCl₂

Molecular mass = mass of Calcium + mass of chlorine

Molecular mass = 40 + 2(35.5)

                          = 40 + 71

                         = 111 g

2.- Calculate the mles of CaCl₂

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

                           5.3 g             -------------------   x

                           x = (5.3 x 1) / 111

                           x = 0.048 moles

3.- Calculate molarity

Molarity = 0.048 / 2.5

Molarity = 0.02
