Explanation:

The given data :

Volume ( V ) = 100 liter = 0.001 * 100 m³ = 0.1 m³

Temperature ( T) = 20° C = 273 + 20 = 293 K

Pressure ( P ) = 2 atm = 2 * 1.01 * 10⁵ pa = 202000 Pa

We know the ideal gas equation.

PV = mRT

m = mass of the gas

R = gas constant of H₂S = 243.96 J/KgK

Substituting the values in equation,

202000 * 0.1 = m * 243.96 * 293

m = 202000*0.1/243.96*293

m=282.4g
