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.

Answers

Answer from: accounting73

The answer to your question is: 0.02 M

Explanation:

Data

mass = 5.57 g

volume = 2.50 L

Formula

Molarity = $\frac{moles}{volume (liters)}$

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

$Molarity = \frac{0.050}{2.5}$

Molarity = 0.02
