The volume fraction of methane in natural gas is 92%. How much of this gas mixture will contain 4.6 ml of methane?

Natural gas is a mixture of low molecular weight hydrocarbons.

To find the volume of the gas mixture, which will contain a given amount of methane, we compose the ratio:

If 92% of the gas contains 4.6 ml of methane, then 100% of the gas contains x.

x = 4.6 * 100/92 = 5 ml.
