Answer:
3. 107 atm
Explanation:
First, we will calculate the moles of each gas by dividing its mass by its molar mass.
nCHCl₃ = 10.2 g/(119.38 g/mol) = 0.0854 mol
nCH₄ = 0.322 g/(16.04 g/mol) = 0.0201 mol
The total number of moles is 0.0854 mol + 0.0201 mol = 0.1055 mol.
The absolute temperature is 345°C + 273.15 = 618 K
We can find the pressure of the gaseous mixture using the ideal gas equation.
P × V = n × R × T
P = n × R × T / V
P = 0.1055 mol × 0.08206 atm.L/mol.K × 618 K / 0.0500 L
P = 107 atm
