# What is the resulting molarity of solution when 2g of NaOH is dissolved in 500 ml of water? (molar mass of NaOH=40.)?

$\text{Molarity}$ $=$ $0.10 \cdot m o l \cdot {L}^{-} 1$ with respect to $N a O H$.
$\text{Molarity}$ $=$ $\text{Moles of solute"/"Volume of solution}$
$\text{Molarity}$ $=$ $\frac{2 \cdot g}{40.0 \cdot g \cdot m o {l}^{-} 1} \times \frac{1}{500 \cdot m L \times {10}^{-} 3 \cdot L \cdot m {L}^{-} 1}$
$=$ ??mol*L^-1.
