A sample of carbon monoxide was collected over water at a total pressure of 752 torr and a temperature of 15°C. What is the pressure (in torr) of the carbon monoxide?

1 answer

VP(HOH) = 12.8 Torr at 15C*
(Google VP(HOH)at 15C)

VP(HOH) + VP(CO)= Total Pressure
12.8Torr + VP(CO) = 752Torr
VP(CO) = (752-12.8)Torr = 739.2 Torr
