Vedclass · Answer

(B) Molarity $(M)$ is defined as the number of moles of solute per litre of solution.$M = \frac{	ext{Number of moles of solute}}{	ext{Volume of solution in litres}}$First,calculate the number of moles of $NaOH$:$	ext{Moles of } NaOH = \frac{	ext{Mass}}{	ext{Molar mass}} = \frac{4 \,g}{40 \,g \,mol^{-1}} = 0.1 \,mol$Next,convert the volume of the solution to litres:$250 \,mL = 0.250 \,L$Now,calculate the molarity:$M = \frac{0.1 \,mol}{0.250 \,L} = 0.4 \,mol \,L^{-1} = 0.4 \,M$
