A scuba tank contains a mixture of oxygen (O2) and nitrogen (N2) gas. The oxygen has a partial pressure of PO2=5.62MPa. The tota

The partial pressure of nitrogen gas is calculated to be 21.16 MPa. The partial pressure of oxygen equates to 5.62 MPa, and the overall gas pressure is stated as 26.78 MPa. This adheres to the principle that the total pressure in a gas system equals the sum of all individual gas partial pressures. Thus, the total pressure in the system reflects the sum of the partial pressures of nitrogen and oxygen. Accordingly, the partial pressure for nitrogen can be derived as follows: Total pressure minus the partial pressure of oxygen. Thus resulting in: 26.78 - 5.62, which gives a partial pressure of nitrogen at 21.16 MPa.

The nitrogen gas partial pressure in the tank is calculated to be 21.16 MPa. This is based on Dalton's Law, which states that for a gas mixture under constant conditions, the total pressure equals the sum of all individual partial pressures. The mixture involves oxygen and nitrogen, so you can express the total pressure as the sum of their individual partial pressures. Given that the total pressure stands at 26.78 MPa and the partial pressure of oxygen is 5.62 MPa, you can set up the equation: Total pressure equals the sum of both partial pressures. Solving it gives you 26.78 = 5.62 + (Partial Pressure of Nitrogen gas), leading to a final result of 21.16 MPa for the nitrogen.
