About Ideal Gas Equation
The ideal gas equation, PV = nRT, relates pressure, volume, amount and absolute temperature when gas particles are assumed to have negligible volume and no intermolecular forces. Applications include finding molar mass, density or an unknown gas variable, with careful use of Kelvin temperature and consistent units, and comparison with real-gas behaviour.

If the temperature of an ideal gas in a sealed, rigid container is increased to 1.5 times the initial value (in K), the density of gas:
What percent of a sample of nitrogen must be allowed to escape if its temperature, pressure and volume are to be changed from 220°C, 3.0 atm and 1.65 L to 110°C, 0.7 atm and 1.0 L, respectively?
A vessel has N2 gas and water vapours at a total pressure of 1 atm. The partial pressure of water vapours is 0.3 atm. The contents of this vessel are transferred to another vessel having one third of the capacity of original volume, completely at the same temperature. The total pressure of this system in the new vessel is:
Blood circulation in human body provides O2 and emits CO2. The concentration of O2 and CO2 is variable, but on an average 0.02 g O2 and 0.08 g CO2 present in an 100 ml of blood. Find the volume of O2 and CO2 in the blood of human (assuming 9.5 L) at 1 atm and 37oC body temperature.
