Question

The partial pressures of the gases in a mixture are 0.255 atm 0, 3.24 atm Ny,

Answer 1

Answer:

4.945 atm

Explanation:

• Based on Dalton's law of Partial pressure, the total pressure of a mixture of gases is equivalent to the sum of individual partial pressures of the gases in the mixture.

• That is;

$Pt = P1+P2+P3+P4+............+ Pn$

In this case;

Partial pressure of Oxygen, P(O) = 0.255 atm

Partial pressure of N, P(N) = 3.24 atm

Partial pressure of Ar, P(Ar) = 1.45 atm

Therefore;

P(total) = P(O) + P(N) + P(Ar)

           = 0.255 atm + 3.24 atm + 1.45 atm

           = 4.945 atm

Therefore, the total pressure of the mixture is 4.945 atm
