The pressure of the gas that has 3.00mol sample of CO2(g) is in a rigid 6.00L container at 400°C is 27.6atm.
The pressure of a gas can be calculated using the ideal gas law equation as follows:
PV = nRT
Where;
P × 6 = 3 × 0.0821 × 673
6P = 165.76
P = 165.76 ÷ 6
P = 27.6atm
Therefore, the pressure of the gas that has 3.00mol sample of CO2(g) is in a rigid 6.00L container at 400°C is 27.6atm.
