How many moles of H2O
moles of H2O are needed to produce 55.7 moles of H2?

55.7 moles of are needed to produce the given amount of

Explanation:

The number of moles is defined as the ratio of the mass of a substance to its molar mass.

The equation used is:

......(1)

Given values:

Moles of = 55.7 moles

The chemical equation for the decomposition of water follows:

By the stoichiometry of the reaction:

If 2 moles of hydrogen gas is produced from 2 moles of water

So, 55.7 moles of hydrogen gas will be produced by = of water

Hence, 55.7 moles of are needed to produce the given amount of
