NCERT · Class 11 · Chemistry · Some Basic Concepts of ChemistryWhat is the molarity of a solution containing $4\text{ g}$ of $\text{NaOH}$ dissolved in $250\text{ mL}$ of solution?
Step-by-Step Solution
Moles of $\text{NaOH} = \frac{4\text{ g}}{40\text{ g/mol}} = 0.1\text{ mol}$. \nVolume of solution in liters $= \frac{250}{1000} = 0.25\text{ L}$.
$\text{Molarity} = \frac{\text{Moles of solute}}{\text{Volume of solution in L}} = \frac{0.1}{0.25} = 0.4\text{ M}$.
