Natural gas is a mixture of many substances, primarily CH4, C2H6, C3H8, and C4H10. Assuming that the total pressure of the gases is 1.48 atm and that their mole ratio is 94 : 4.0 : 1.5 : 0.50, calculate the partial pressure in atmospheres of each gas:

SEE EXPLANATION

Explanation:

We have the mole ratio as; 94 : 4.0 : 1.5 : 0.50

This implies that the total number of natural gas is; 94 + 4.0 + 1.5 + 0.50 = 100 moles

Recall that partial pressure = mole fraction * total pressure

For CH4 = 94/100 * 1.48 atm = 1.39 atm

For C2H6 = 4/100 * 1.48 atm = 0.0592 atm

For C3H8 = 1.5/100 * 1.48 atm = 0.0222 atm

For C4H10 = 0.5/100 * 1.48 atm = 0.0074 atm
