answer: the partial pressure of hydrogen is 93.9 kpa.
to calculate the partial pressure of hydrogen, we will follow dalton's law.
this law states that the total pressure of a mixture of gases is equal to the sum of the individual pressures exerted by the constituent gases.
according to the question,
we are given:
putting values in above equation, we get:
hence, the partial pressure of hydrogen is 93.9 kpa.
