Question

Pure hydrogen sulphide is stored in a tank of 100 litre capacity at and 2 atm pressure. The mass of the gas will be.

• A. 34 g
• B. 340 g
• C. 282.4 g
• D. 28.24 g

Answer 1

Answer: (C)

282.4 g

Answer 2

$n = \frac { P V } { R T } = \frac { m } { M }$

$m = \frac { M P V } { R T } = \frac { 34 \times 2 \times 100 } { 0.082 \times 293 } = 282.4 \mathrm { gm }$
