1.2 × 10³ L
Explanation:
Step 1: Calculate the total number of gaseous moles
n = nH₂ + nCl₂ = 100 mol + 100 mol = 200 mol
Step 2: Convert 30 °C to Kelvin
We will use the following expression.
K = °C + 273.15 = 30 + 273.15 = 303 K
Step 3: Calculate the volume of the container
We will use the ideal gas equation.
P × V = n × R × T
V = n × R × T / P
V = 200 mol × (0.0821 atm.L/mol.K) × 303 K / 4 atm = 1.2 × 10³ L
