In what ratio a 80% (wt./vol.) solution of $H_{2} S O_{4}$ be mixed to 20% (wt./vol.) of $H_{2} S O_{4}$ to produce 40% (wt./vol.) $H_{2} S O_{4}$ solution

Options:

Answer:

Solution:

Let, $V_{1} m L$ of 80% and $V_{2} m L$ of 20% are mixed
$V_{1} \times 80 + V_{2} \times 20 = 40 (V_{1} + V_{2})$
So $40 V_{1} = 20 V_{2}$
So $\frac{V_{1}}{V_{2}} = \frac{1}{2}$
