Answer:
422 torr
Explanation:
According to Dalton's law of partial pressure, the total pressure exerted by a mixture of gases is the sum of their individual/partial pressure. Mathematically, this can be expressed as:
[tex]P_{total} = P_{1} + P_{2} + ........+ P_{n}[/tex]
In this case, [tex]P_{SO2}[/tex] = 137 torr, [tex]P_{Cl2}[/tex] = 285 torr, hence
[tex]P_{SO2Cl2}[/tex] = [tex]P_{SO2} + P_{Cl2}[/tex]
= 137 + 285
= 422 torr
The partial pressure of SO2Cl2 in this mixture is 422 torr.
