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

Are three mixtures:

CO₂ , SO₂ , H₂O so :

25 Kpa x 3 = 75 Kpa

Answer 2

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.
