Solution

Q.
The molarity of a 70% (mass/mass) aqueous solution of a monobasic acid (X) is _____ $\times 10^{- 1}$ M (Nearest integer)

[Given: Density of aqueous solution of (X) is 1.25 g ${mL}^{- 1}$ Molar mass of the acid is 70 g ${mol}^{- 1}$ ] [2025]

Ans.
(125)

$M = \frac{(% w / w) \times d \times 10}{M_{solute}}$

$M = \frac{70 \times 1.25 \times 10}{70} M = 125 \times 10^{- 1} M$
