Chemistry - Individual Gas Laws

Question

A steel tank contains a mixture of Ar and He gases. If the partial pressure of helium in the tank is 1,185 mmHg, and the partial pressure of argon is 4,013 mmHg, what is the total pressure in the tank (in atm)?

Answer 1

The total pressure is the sum of the partial pressures of each gas that is present.

P_He = 1185 mm Hg

P_Ar = 4013 mm Hg

P_total = 1185 mm + 4013 mm = 5198 mm Hg
