Gas Laws

Change in gas pressure when volume is decrased

A volume of gas is decreased by half while the temperature remains constant. How much does the gas pressure change? (2) State the relationship between the volume and pressure of a gas when the temperature is held constant (Boyles law). (3) Does data taken in an experiment support the idea that the pressure times the volume

The Ideal Gas Law to Determine the Molecular Weights of Gas

At a given temperature a certain number of grams of CH4, when placed in a 10 L vessel, exerts a pressure of 0.240 atm. An equal number of grams of gas B, when placed in a 12 L container at the same temperature, exerts a pressure of 0.145 atm. Calculate the approximate molecular weight of gas B.
