Detailed Solution

$\begin{aligned} m_{Solution} = \frac{100}{80} \times 20 = 250 gm \\ V_{Solution} = \frac{250}{0.95} = \frac{5000}{19} ml \\ m_{H_{2} S} = 250 - 200 = 50 gm \end{aligned}$

Molarity of solution $= \frac{\frac{50}{54}}{\frac{5000}{19}} \times 1000 = \frac{95}{17} M$

Molality of solution $= \frac{\frac{50}{34}}{200} \times 1000 = \frac{125}{17} m$
