Document Summary

Where p= pressure, v= volume, n= number of moles, r= gas constant, t= temperature. When using the ideal gas law, the value of r changes depending on the units of pressure and volume. Temperature will always be in kelvin when using the ideal gas law. Density: the ratio of mass to volume density= molar mass/molar volume. Generally given in g/l and assuming volume of 1 mole gas at stp = 22. 4 l. The total pressure of gases in a closed container is the sum of all the individual gas pressure. Mole fraction: the ratio of the moles of a single component to the total number of moles in the mixture.
