The volume fraction of a substance is a value that characterizes the ratio of the volume of a given substance to the volume of the entire mixture of substances. We know the volume fraction and volume of the substance. Based on the definition, we find the volume of a mixture of substances we need, that is, natural gas, taking it for x:
1) 94% = (20 * 100%) / x
2) x = (20 * 100%) / 94% = 21.276595745 liters
Reducing to hundredths, we get 21.28 liters
Answer: 20 liters of methane is contained in 21.28 liters of natural gas.
