Answer:
Explanation:
Since the <em>gas mixture</em> is <em>ideal</em>, the <em>composition</em> by <em>volume</em> is equal to the composition by moles.
Thus, the mole composition is:
Use a basis of 100 moles and find the mass of each gas, using its corresponding molar masss:
- N₂: 30 moles × 28g/mol = 840 g
- O₂: 30 moles × 16g/mol = 480 g
- H₂: 40 moles × 2g/mol = 80 g
Total mass = 840g + 480g + 80g = 1,400g
Then, the mass fraction of oxgygen is the mass of oxygen divided by the total mass of the gas mixture:
Which in percentage is 34.29%.
Rounded to the nearest integer that is 34% ← answer
