The molarity of a $70 \%$ (mass $/$ mass) aqueous solution of a monobasic acid $(\mathrm{X})$ is __________ $\times 10^{-1}$ M(Nearest integer)
[Given: Density of aqueous solution of (X) is $1.25 \mathrm{~g} \mathrm{~mL}^{-1}$
Molar mass of the acid is $70 \mathrm{~g} \mathrm{~mol}^{-1}$ ]

Question

Moles of solute $=\frac{70}{70}=1$ Volume of solution $=\frac{100}{1.25}=80 \mathrm{~mL}$ $\begin{aligned} & M=\frac{1}{80} 	imes 1000=12.5 \ & M=125 	imes 10^{-1} \end{aligned}$
