Question

41.0 g of barium hydroxide, $\mathrm{Ba(OH)_2}$ is dissolved in water. The final volume of the solution is 2.00 L. What is the molarity of the solution? The molar mass of $\mathrm{Ba(OH)_2}$ is 171.3 g/mol.

Answer:

Molarity (molar concentration) of the solution is:

$$C = \frac{n}{V} = \frac{m}{M \cdot V}$$ $$C = \frac{m}{M \cdot V} = \frac{41.0}{171.3 \cdot 2.00} = 0.12 \, \text{mol/L}$$

Answer: 0.12 M
