Question

1. A 15.8 liter solution contains 10.4 moles of NaCl. What is its concentration?
​

Answer 1

= 0.658 M

Step-by-step explanation:

Molarity also known as concentration is given by the formula;

Concentration = Number of moles / Volume in liters

In this case;

Number of moles = 10.4 moles

Volume = 15.8 liters

Concentration = 10.4 moles/ 15.8 liters

= 0.658 moles/liter

= 0.658 M
