P V = nk T
pressure, volume Temperature, n umber of molecules ( or moles of molecules) and k the appropriate constant in units. ( I forget exactly)
total pressure = sum of individual pressures of individual types of gasses.
Gas laws especially related to mole, and atomic weights was NOT easy to figure out
Ask Avogadro who sat around counting that big 6.23 * 10^23 number ( science joke)
