Answer from: Lorettareneemills

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.

For CH₄:

Percentage of CH₄ = 90%

Total = 100%

Mole fraction CH₄ =?

Mole fraction = mole / total

Mole fraction CH₄ = 90 / 100

Mole fraction CH₄ = 0.9For C₂H₆:

Percentage of C₂H₆ = 8.9%

Total = 100%

Mole fraction C₂H₆ =?

Mole fraction = mole / total

Mole fraction C₂H₆ = 8.9 / 100

Mole fraction C₂H₆ = 0.089For C₃H₈:

Percentage of C₃H₈ = 1.1%

Total = 100%

Mole fraction C₃H₈ =?

Mole fraction = mole / total

Mole fraction C₃H₈ = 1.1 / 100

Mole fraction C₃H₈ = 0.011

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 of CH₄ =?

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 of C₂H₆ =?

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 of C₃H₈ =?

Partial pressure = mole fraction × Total pressure

Partial pressure of C₃H₈ = 0.011 × 307.2

Partial pressure of C₃H₈ = 3.38 KPa

Answer from: laraejackson75

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 answer is a and have a great day

Answer from: Quest

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
