Question

$H_2{SO}_4$ is labeled as $9.8$ by weight. Specific gravity of $H_2{SO}_4$ is $1.8$. The volume of the acid to be taken to prepare $1000ml$ of $0.18M$ solution is:

• A. $10ml$
• B. $100ml$
• C. $740ml$
• D. $360ml$

Answer 1

Answer: (B)

$100ml$

$M=10\times d\times y/$gram molecular weight

$M=10\left(1.8\right)\frac{9.8}{98}$

$M=1.8$

$M_1\times V_2=M_2\times V_1$

$\left(1.8\right)V_2=1000\left(0.18\right)$

$V_2=100$ ml
