Question

Hydrogen and Oxygen combine in ratio of 1:8 by mass to form water . what mass of oxygen gas would be required to react completely with 3g of hydrogen gas ?
please give full solution​

Answer 1

Explanation:

1 g of hydrogen reacts with = 8 g of oxygen

∴ 3 g of hydrogen reacts with = 8 × 3 = 24 g of oxygen

Thus, 24 g of oxygen gas would be required to react completely with 3 g of hydrogen gas.

Answer 2

Explanation:

Hydrogen and oxygen combine in the ratio of 1 : 8 by mass to form water. What mass of oxygen gas would be required to react completely with 3 g of hydrogen gas? Thus, 24 g of oxygen gas would be required to react completely with 3 g of hydrogen gas.
