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.
[tex]p_{total}=p_A+p_B+p_C[/tex]
Thus [tex]p_{total}=p_{CO_2}+p_{SO2}+p_{H_2O}[/tex]
Given:
[tex]p_{CO_2}=25kPa[/tex]
[tex]p_{SO_2}=25kPa[/tex]
[tex]p_{H_2O}= 25kPa[/tex]
Thus [tex]p_{total}=25Pa+25kPa+25kPa[/tex]
[tex]p_{total}=75kPa[/tex]
Thus the pressure of mixture of gases is 75 kPa.
