If 4g of Hydrogen reacts xg of oxygen to give 36g of water.How much Oxygen was used up in this process.
Answers
The amount of oxygen used to produce 36 g of water is 32 g.
Explanation:
The chemical reaction for the formation of water is:
2H₂ + O₂ → 2H₂O
Now,
36 × 1/18 = 2 moles of water
4 g of H₂ × 1/2 = 2 moles of hydrogen
On applying the law of conservation of mass, two moles of hydrogen and 1 mole of oxygen reacts to produce 2 moles of water.
Thus, one mole of oxygen is required to produce 2 moles of water.
1 mole of oxygen × 32 g/mole of water = 32 g of oxygen
