Pure hydrogen sulfide is stored in a tank of 100 liter capacity at 200C and 2 atm pressure. The mass of the gas will be:

The correct option is D 282.4 gThe correct answer is Cwe know that number of moles in hydrogen sulfide =34Explanation:-PVRT=mMm=mpvRT=34×2×1000.082×293=282.4 g

Pure hydrogen sulfide is stored in a tank of $100$ liter capacity at $20^{0} C$ and $2 a t m$ pressure. The mass of the gas will be:

The correct option is D $282.4 g$
The correct answer is C
we know that number of moles in hydrogen sulfide =34
Explanation:- $\frac{P V}{R T} = \frac{m}{M}$
$m = \frac{m p v}{R T} =$
$\frac{34 \times 2 \times 100}{0.082 \times 293}$
=282.4 g
