Law of Partial Pressures: For a mixture of gases in a container, the total pressure exerted is the sum of the pressures that each gas  would exert if it were alone. P total  = P 1  + P 2  + P 3  + ... where P 1  is the partial pressure of the first gas, P 2  is the partial pressure of the second gas, P is the partial  pressure of third gas, etc. .. If each gas behaves ideally, then the partial pressure of each gas can be calculated  from the ideal gas law. P 1  = n 1  R T / V,        P 2  = n 2  R T / V,             P 3  = n 3  R T / V,     . .. Remember all the different gases are together in a single container of volume V and at a temperature T. We can  substitute these expressions into the sum above and get P total  = n 1  R T / V + n 2  R T / V + n 3  R T / V + . .. which we can rewrite as
