# What is the concentration with respect to sodium hydroxide if a 10*g mass of same is dissolved in a 1*L volume of solution?

$0.25 \cdot m o l \cdot {L}^{-} 1$?
Take $10 \cdot g$ sodium hydroxide, and dissolve this to a litre volume.
$\text{Concentration}$ $=$ $\frac{\frac{10.0 \cdot g}{40.00 \cdot g \cdot m o {l}^{-} 1}}{1.00 \cdot L}$ $=$ $0.25 \cdot m o l \cdot {L}^{-} 1$ as required.
