Question

calculate the molarity of a solution made by dissolving 3.7 moles of sodium chloride in 8.7 liters of water? ​

Answer 1

Molarity = 0.425 M

Step-by-step explanation:

Given data:

Number of moles = 3.7 mol

Volume of solution = 8.7 L

Molarity of solution = ?

Solution:

Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.

Formula:

Molarity = number of moles of solute / L of solution

Molarity = 3.7 mol/8.7 L

Molarity = 0.425 M
