The molarity of a 70 % (mass / mass) aqueous solution of a monobasic acid ( X ) is __________ 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 ]

Correct answer

0

Step-by-step solution

Moles of solute = 70 70 =1 Volume of solution = 100 1.25 =80 ~mL aligned & M= 1 80 1000=12.5 & M=125 10⁻¹ aligned
