Asample of gas isolated from unrefined petroleum contains 90.0% ch4, 8.9% c2h6, and 1.1% c3h8 at a total pressure of 307.2 kpa. what is the partial pressure of each component of this gas?

The partial pressure of each component of the gas are:

1. The partial pressure of CH₄ is 276.48 KPa

2. The partial pressure of C₂H₆ is 27.34 KPa

3. The partial pressure of C₃H₈ is 3.38 KPa

We'll begin by calculating the mole fraction of each gas.

Percentage of CH₄ = 90%

Total = 100%

Mole fraction = mole / total

Mole fraction CH₄ = 90 / 100

Percentage of C₂H₆ = 8.9%

Total = 100%

Mole fraction = mole / total

Mole fraction C₂H₆ = 8.9 / 100

Percentage of C₃H₈ = 1.1%

Total = 100%

Mole fraction = mole / total

Mole fraction C₃H₈ = 1.1 / 100

Finally, we shall determine the partial pressure of each gas. This can be obtained as follow:

1. Determination of the partial pressure of CH₄

Mole fraction CH₄ = 0.9

Total pressure = 307.2 KPa

Partial pressure = mole fraction × Total pressure

Partial pressure of CH₄ = 0.9 × 307.2

Partial pressure of CH₄ = 276.48 KPa

2. Determination of the partial pressure of C₂H₆

Mole fraction C₂H₆ = 0.089

Total pressure = 307.2 KPa

Partial pressure = mole fraction × Total pressure

Partial pressure of C₂H₆ = 0.089 × 307.2

Partial pressure of C₂H₆ = 27.34 KPa

3. Determination of the partial pressure of C₃H₈

Mole fraction C₃H₈ = 0.011

Total pressure = 307.2 KPa

Partial pressure = mole fraction × Total pressure

Partial pressure of C₃H₈ = 0.011 × 307.2

Partial pressure of C₃H₈ = 3.38 KPa

276.48 atm → CH₄

27.3 atm → C₂H₆

3.38 atm → C₃H₈

Explanation:

Percentages of each gas, are the mole fraction

0.9 CH₄

0.089 C₂H₆

0.011 C₃H₈

Mole fraction = Partial pressure each gas/ Total pressure

0.9 = Partial pressure CH₄ / 307.2 kPa

307.2 kPa . 0.9 = 276.48 atm

0.089 = Partial pressure C₂H₆ / 307.2 kPa

307.2 kPa . 0.089 = 27.3 atm

0.011 = Partial pressure C₃H₈ / 307.2 kPa

307.2 kPa . 0.011 = 3.38 atm

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
