Correct Answer – `(10.42)`
`93% H_(2)SO_(4)` solution weight by weight by volume indicates that there is `93 g H_(2)SO_(4)` in `100` mL of solution.
If we consider `100` mL solution, Weight of solution `=184 g`
Weight of `H_(2)O` in `100` mL solution, weight of solution `=184-93=91 g`
`implies` Molality `=(“Moles of solute”)/(“Weight of solvent (g)”)xx1000`
`=93/98xx1000/91=10.42`
