The partial pressure of carbon dioxide is 75 torr.
Dalton's theory of gas states that total pressure of the mixture of gas sample is equal to the sum of the partial pressure of all the gases present in that sample.
Given that,
On putting values, we get
Partial pressure of carbon dioxide = 825 - (600 + 150) = 75 torr
Hence Partial pressure of carbon dioxide is 75 torr.
