Question

Find the mass percentage.
carbon and hydrogen in methane​

Answer 1

Explanation:

mass % C = (mass of 1 mol of carbon/mass of 1 mol of CO2) x 100. mass % C = (12.01 g / 44.01 g) x 100. mass % C = 27.29 %

What is the mass percentage of hydrogen?

The percentage of an element in a compound is 100 times the fraction, so for water the mass percent hydrogen is 11.11% and the mass percent oxygen is 88.89%.

Answer 2

Explanation:

In hydrogen methane the mass percentage is 25.14%

In carbon methane the mass percentage is 74%...
