Video transcript

Hi everyone. So we have the value of A. For xenon, which is 4.19 liter square atmosphere about more square. And this is a constant in the Van der Waals equation and were asked to determine the value of Xenon. If the pressure was measured in bars, Recall that one atmosphere, People's 1.013 25 bar. We have 4.19 leader square times atmosphere about about mile square. And in one atmosphere We have 1. 25 bars. And these cancel out. We're gonna get 4.25 later square times bar about about most squared. Thanks for watching my video and I hope it was helpful.

You have a gas at 25 C confined to a cylinder with a movable piston. Which of the following actions would double the gas pressure? (a) Lifting up on the piston to double the volume while keeping the temperature constant (b) Heating the gas so that its temperature rises from 25 C to 50 C, while keeping the volume constant (c) Pushing down on the piston to halve the volume while keeping the temperature constant.

Textbook Question

Suppose you are given two 1-L flasks and told that one contains a gas of molar mass 30 and the other a gas of molar mass 60, both at the same temperature. The pressure in flask A is x atm, and the mass of gas in the flask is 1.2 g. The pressure in flask B is 0.5x atm, and the mass of gas in that flask is 1.2 g. Which flask contains the gas of molar mass 30, and which contains the gas of molar mass 60?

Textbook Question

Suppose you are given two flasks at the same temperature, one of volume 2 L and the other of volume 3 L. The 2-L flask contains 4.8 g of gas, and the gas pressure is x atm. The 3-L flask contains 0.36 g of gas, and the gas pressure is 0.1x. Do the two gases have the same molar mass? If not, which contains the gas of higher molar mass?
