Question

When 12.0 grams of the element carbon react with 4.00 grams of element hydrogen, natural gas is produced. There is no leftover carbon or hydrogen when these quantities are used. How much carbon and hydrogen would you need to make 100.0 grams of natural gas.

Answer 1

Answer: 75g of Carbon and 25g of Hydrogen

Explanation: the ratio of carbon to hydrogen is 12:4

Total ratio = 16

Mass of carbon in the natural gas

= (12/16) x 100 = 75g

Mass of Hydrogen in the natural gas = (4/16) x 100 = 25g
