Find the molality of 1.0 L solution of 90% `H_2SO_4` by weight/volume. The density of the solution is 1.47 `gc c^(-1)`

Text Solution

Verified by Experts

(a). `90% H_2SO_4 (weight)/(volume)implies(90g)/(100mL)`
`implies(Mass)/(L)=900g`
`("Mass of solution")/(L)=1000xx1.47=1470g`
`impliesMass of H_2O=1470-900=570g`
`m=((900)/(98))/(570)xx1000=16.11`
