Question

what is the pressure of a mixture of co2, so2, and h2o gasses, if each gas has a partial pressure of 25 kpa?

Answer 1

Answer: 75 kPa

Explanation: According to Dalton's law, the total pressure of a mixture of gases is the sum of individual pressures exerted by the constituent gases.

$p_{total}=p_A+p_B+p_C$

Thus $p_{total}=p_{CO_2}+p_{SO2}+p_{H_2O}$

Given:

$p_{CO_2}=25kPa$

$p_{SO_2}=25kPa$

$p_{H_2O}= 25kPa$

Thus $p_{total}=25Pa+25kPa+25kPa$

$p_{total}=75kPa$

Thus the pressure of mixture of gases is 75 kPa.

Answer 2

Are three mixtures:

CO₂ , SO₂ , H₂O  so :

25 Kpa x 3 =  75 Kpa
