A container holds 6.4 moles of gas. Hydrogen gas makes up 25% of the total moles in the container. If the total pressure is 1.24 atm. What is the partial pressure of hydrogen? Use StartFraction P subscript a over P subscript T EndFraction equals StartFraction n subscript a over n subscript T EndFraction.. 0.31 atm 0.93 atm 5.2 atm 31 atm

Answer:

0.31 atm

Explanation:

According to the Dalton's law of partial pressure, the total pressure of the gaseous mixture is equal to the sum of the pressure of the individual gases.

Also, the partial pressure of the gas is equal to the product of the mole fraction and total pressure.

Given, for hydrogen gas, it is 25% of the total moles.

So, Mole fraction = 0.25

Total pressure = 1.24 atm

Partial pressure of hydrogen = 0.25 * 1.24 atm = 0.31 atm
