A mixture of gases consists of N2, O2, H2 and F2. The total pressure of the mixture is 511.56 kPa. The pressure of the N2 is 584 mm Hg, the pressure of the O2 is 196 kPa and the pressure of the H2 is standard pressure. What is the pressure of the F2 (in mm Hg)?

Step-by-step explanation:

The total pressure of a gas is the sum of the partial pressures of the gases that it consists of. It means that

N2 + O2 + H2 + F2 = pressure of mixture

1 kpa = 7.50061683 mmhg

The total pressure of the mixture is 511.56 kPa. Converting to mmHg, it becomes

511.56 × 7.50061683 = 3837.02 mmhg

The pressure of the O2 is 196 kPa. Converting to mmhg, it becomes

196 × 7.50061683 = 1470.12 mmhg

Since the the pressure of the H2 is standard pressure, it means that the pressure is 760 mmhg

Also, pressure of the N2 is 584 mm Hg

Therefore,

1470.12 + 760 + 584 + F2 = 3837.02

2814.12 + F2 = 3837.02

F2 = 3837.02 - 2814.12

F2 = 1022.9 mm Hg
