What is the molarity of a 250.0 ml aqueous solution of sodium hydroxide that contains 15.5 grams of solute?
Whitepunk [10]

The molar concentration of the solution is 1.55 mol/L.


1. Convert grams to moles.


\text{Moles of NaOH} = 15.5 \text{g NaOH} \times \frac{\text{1 mol NaOH}}{\text{40.00 g NaOH}} = \text{0.3875 mol NaOH}\\

2. Convert millilitres to litres


V = 250.0 \text{mL} \times \frac{\text{1 L}}{\text{1000 mL}} = \text{0.2500 L}\\

3. Calculate the molar concentration (c)


c = \frac{\text{moles}}{\text{litres}} = \frac{\text{0.2875 mol}}{\text{0.2500 L}} = \textbf{1.55 mol/L}
