Assuming that only the listed gases are present, what would be the mole fraction of oxygen gas be for each of the following situations? A gas sample of 2.31 atm of oxygen gas and 3.75 atm of hydrogen gas that react to form water vapor. Assume the volume of the container and the temperature inside the container does not change.

The mole fraction of oxygen gas : 0.381

Given

2.31 atm Oxygen

3.75 atm Hydrogen

Required

The mole fraction of Oxygen

Solution

Dalton Law's of partial pressure

P tot = P₁ + P₂ + ..Pₙ

Input the value :

P tot = P O₂ + P H₂

P tot = 2.31 atm + 3.75 atm

P tot = 6.06 atm

The mole fraction of O₂ (X O₂):

P O₂ = X O₂ x P tot

X O₂ = P O₂ / P tot

X O₂ = 2.31 /6.06

X O₂ = 0.381

Several characters in The Land face inequality. This unfairness is bad for characters because it affects them in a negative way. Paul is picked on when he is young because he can read and has special privileges because he is part white. The boys who pick on him do it because they are angry about the inequality. However, later in the novel Paul experiences inequality too. He is not allowed to eat with his white family when company comes, and he is not allowed to go to the same school as his white brother. Paul feels like his family is divided instead of together.
