Amixture of he, ne, and n2 gases are a pressure of 1.348. if the pressures of he and ne are 0.124 atm, what is the partial pressure of n2 in the mixture ?

Answer :  The partial pressure of in the mixture is, 1.224 atm

Solution :

According to the Dalton's law, the total pressure of the gas is equal to the sum of the partial pressure of the mixture of gasses.

where,

= total partial pressure of = 1.348 atm

= partial pressure of helium

= partial pressure of neon

= partial pressure of nitrogen

As we are given that,

Now put all the given values in above expression, we get the partial pressure of the nitrogen gas in the mixture.

Therefore, the partial pressure of in the mixture is, 66 Kpa

b is the correct answer

mark me brainliest and hope this

personal, she chose to do it.
