Answer:
93.4 kPa
Explanation:
- According to Dalton law of partial pressure, the total pressure of a mixture of gases is equivalent to the sum of partial pressures of individual gases.
- That is, P(total) =P₁ + P₂ +P₃ , where P₁, P₂ and P₃ are partial pressures of individual gases.
In this case,
P(Po) = 20.0 kPa
P(PN) = 46.7 kPa
P(Phe) = 26.7 kPa
Therefore, the total partial pressure will be;
P(total) = 20.0 kPa + 46.7 kPa + 26.7 kPa
= 93.4 kPa
Therefore, the total pressure of the ga mixture is 93.4 kPa
