Question

What mass of carbon dioxide is produced from the complete combustion of `8.50*10^-3` `g` of methane?

Answer 1

3.145 X `10^-3` g

Explanation:

The equation for the combustion of Methane is as follows.

C`H_4` + `O_2` ------> C`O_2` + 2 `H_2`O

One mole of Methane on burning produces one mole of Carbon Dioxide or using molar masses , I can write,

16 g of Methane produces 44 g of Carbon dioxide
using ratio and proportions , we can get the answer;

mass of C`O_2` = [ 16g C`H_4` / 44 g C`O_2` ] x 8.50 x `10^-3` of C`H_4`

                          = 0.37 x 8.50 x  #10^-3# g

                          = 3.145 X # 10^-3# g
