A gaseous mixture was prepared by taking
equal number of moles of Helium and Neon. If
the total pressure of the mixture was found to
be 10 atm, the partial pressure of Helium in the
mixture is ----

View answer and explanation

Correct option: B

5 atm

Option B (5 atm) is correct because the partial pressure of a gas in a mixture is equal to its mole fraction multiplied by the total pressure. Since the mole fraction of Helium is 0.5, its partial pressure is 5 atm.
