The pressure for 1.0 mol of a gas at 0oC in 3.0 L container is calculated to be 7.5 atm using the ideal gas equation (PV = nRT). The pressure of the gas is measured and found to be 7.1 atm. Which of the following best explains the reason for the discrepancies in the two values?

The best explanation would be that the temperature of the gas has dropped before measuring the pressure.

Relationship between temperature and pressure of gases

According to pressure law, the pressure of a gas is directly proportional to its temperature, provided the volume of the gas remains constant.

Thus, since the initial pressure of the gas was calculated to be 7.5 atm, the temperature of the gas must have dropped in order for the measured pressure to be 7.1 atm.
