The volume fraction of methane in natural gas is 92%. How much of this gas mixture will contain 300 ml of methane?

Given: ϕ (methane) = 92%, or 0.92, V (methane) = 300 ml.
Find: V (natural gas) -?
From the formula for finding the volume fraction of methane ϕ (methane) = V (methane) / V (natural gas), we find the volume of natural gas:
V (natural gas) = V (methane) / ϕ (methane) = 300 ml: 0.92 = 326 ml.
Answer: 326 ml.
