Answer:
Mole fraction N₂ = 0.336
Explanation:
Mole fraction of a gas can be determined in order to know the partial pressure of the gas, and the total pressure, in the mixture.
Total pressure in the mixture: Sum of partial pressure from all the gases
Total pressure = 183 mmHg + 443 mmHg + 693 mmHg =1319 mmHg
Mole fraction N₂ = Partial pressure N₂ / Total pressure
443 mmHg / 1319 mmHg = 0.336
Remember that mole fraction does not carry units
Answer:
The mol fraction of N2 is 0.336
Explanation:
Step 1: Data given
Partial pressure CH4 = 183 mm Hg
Partial pressure N2 = 443 mm Hg
Partial pressure O2 = 693 mm Hg
Step 2: Calculate total pressure
Total pressure = partial pressure CH4 + partial pressure N2 + partial pressure O2
Total pressure = 183 mm Hg + 443 mm Hg + 693 mm Hg
Total pressure = 1319 mm Hg
Step 3: Calculate mol fraction
Mol fraction = partial pressure / total pressure
Mol fraction N2 = 443 mm Hg / 1319 mm Hg
Mol fraction N2 = 0.336
The mol fraction of N2 is 0.336
