Answer:
Mass = 253.4 g
Explanation:
Given data:
Mass of oxygen required = ?
Mass of hydrogen available = 32.0 g
Solution:
Chemical equation:
2H₂ + O₂ → 2H₂O
Number of moles of hydrogen:
Number of moles = mass/molar mass
Number of moles = 32.0 g/ 2.02 g/mol
Number of moles = 15.84 mol
Now we will compare the moles of hydrogen and oxygen:
H₂ : O₂
2 : 1
15.84 : 1/2×15.8 = 7.92 mol
Mass of oxygen required:
Mass = number of moles × molar mass
Mass = 7.92 mol × 32.00 g/mol
Mass = 253.4 g
