Question

The molality of a sulphuric acid solution is $0.2$ M. Calculate the total weight of the solution.

• A. $1000$ g
• B. $1098.6$ g
• C. $980.4$ g
• D. $1019.6$ g

Answer 1

Answer: (D)

$1019.6$ g

$1$ kg or $1000$ g of water contains $0.2$ mol of sulphuric acid which corresponds to $0.2\times 98=19.6g$.
Hence, the total mass of the solution is $1000g+19.6g=1019.6g$.
