Question

If 1.0 mole of methane reacts with oxygen to produce carbon dioxide and water, what mass of water is produced?

Answer 1

Approx. `36*g`

Explanation:

We need a stoichiometric equation to represent the combustion of methane:

`CH_4(g) + 2O_2(g) rarr CO_2(g) + 2H_2O(l)`

Given that the 1 mole of methane reacts, the products are the 1 mole of carbon dioxide, and 2 moles of water, which has a mass of .....?
