Can someone help me with this problem? Determine the moles of oxygen gas (O2) needed to completely react with 1.975 moles of hydrogen gas (H2). 2 H2 (g) + 1 )2 (g) → 2 H2O

Answer 1

2 H₂ (g) + O₂ (g) → 2 H₂O (g)

From the above balanced reaction, 2 moles of H₂ gas reacts with 1 mole of O₂. The mole ratio of H₂ to O₂ is 2:1. Use this mole ratio to setup the stoichiometry conversion.

1.975 mol H₂ x (1 mol O₂ / 2 mol H₂) = 0.9875 mol O₂
