Question

What amount of water produced by combustion of 16g of methane?

Answer 1

Answer:

The amount of water produced by the combustion of 16 gram methane is 36 grams

Answer 2

Answer:

36g

Explanation:

The chemical reaction, that occurs is :-

CH4 +2O2 ––––> CO2+2H2O

We see that one mole of CH4 produces two moles of water on combustion.

mass of CH4 available = 16g

molar mass of CH4 = 16g

So, moles of CH4 = given mass/molar mass = 16g/16g = 1 mole.

So , moles of H2O produced = 2(moles of CH4)

moles of H2O = 2×1 = 2

Molar mass of H2O = 18 g

Mass of H2O produced = moles of H2O × molar mass of H2O = 2×18g = 36g ( Ans )
