Amixture of two gases exerts a total pressure of 2.25 atm. if the partial pressure of one of the gases is 1.43 atm, what is the partial pressure of the other gas in the mixture?

Answer :  The partial pressure of other gas in a mixture is, 0.82 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 = 2.25 atm

= partial pressure of one gas = 1.43 atm

= partial pressure of another gas = ?

Now put all the given values is expression, we get the partial pressure of the another gas.

Therefore, the partial pressure of other gas in a mixture is, 0.82 atm

the answer is 1 i believe
