For scuba dives below 150 ft, helium is often used to replace nitrogen in the scuba tank. If 14.7 g of He(g) and 28.0 g of O₂(g) are added to a previously evacuated 5.35 L tank at 20.°C, calculate the partial pressure of each gas present as well as the total pressure in the tank. Partial pressure of He Partial pressure of 02 Total pressure = atm atm atm
