Part 1. Determine the molar mass of a 0.622-gram sample of gas having a volume of 2.4 L at 287 K and 0.850 atm. Show your work. Part 2. If this sample was placed under extremely low temperature, describe how the actual volume would compare to the predicted volume. Explain your answer.

Part 1:

Part 2: It will be lower.

Explanation:

Hello,

Part 1: In this case, by using the ideal gas equation we can compute the moles of the gas by knowing the pressure, temperature and volume:

Thus, the molar mass by using the mass:

Part 2: In this case, recalling the Charles' law, which states that the volume-temperature relationship is a directly proportional one:

We can see that the lower the temperature, the lower the volume, therefore, for an extremely low temperature an extremely low volume will be occupied by the gas.

Best regards.
