Question

The molality of a sulphuric acid solution is $0.2$. Calculate the total weight of the solution having $1000$ gm of solvent.

• A. $19.6$ g
• B. $1000$ g
• C. $1019.6$ g
• D. $980.4$ g

Answer 1

The correct option is C $1019.6$ g

$m=0.2$ mole/kg
Weight of solvent $=1000$ g
Weight of solute $=0.298=19.6$ g
Total weight of solution $=1000+19.6=1019.6$ ml
