Question

What is the molarity of a solution containing 100 moles of NaCl dissolved in 10 liters of water?

2 mol/L

10 mol/L

0.5 mol/L

5 mol/L

Answer 1

The answer is 10 mol/L

Answer 2

10 mol/L

Step-by-step explanation:

Molarity or concentration is given by the formula;

Molarity = Number of moles/Volume in Liters

In this case; number of moles = 100 and Volume = 10 L

Therefore;

Molarity = 100 moles/10 L

= 10 mol/L
