How many moles of oxygen gas are need to produce 5.53 x 10 moles of water (1) 2 H2g) + Oz(9) 2 H2O(1)

2.765 × × 10³ moles of O₂

Explanation:

The chemical equation to produce water from oxygen and hydrogen is;

2H₂ (g) + O₂ (g) = 2H₂O (l)

From the equation above, we see that;

2 moles of H₂O is produced from 1 mole of O₂

Thus; 5.53 × 10³ moles of H₂O  will require;

(5.53 x 10³ moles of H₂O × 1 mole of O₂)/2 moles of H₂O = 2.765 × × 10³ moles of O₂
