$\text{Molarity} = \frac{0.5}{0.25} = 2 \\ \text{M}$

Q: If you need to prepare 1 L of a 0.2 M NaOH solution, how many grams of NaOH are required? ($\text{Molar mass of NaOH} = 40 \\ \text{g/mol}$)

$0.2 \\ \text{mol} \\ \times 40 \\ \text{g/mol} = 8 \\ \text{g}$

Q: Which of the following is the correct formula for density?

$\text{Density} = \frac{\text{Mass}}{\text{Volume}}$
