A cyclopropane-oxygen mixture is used as an anesthetic. if the final pressure of cyclopropane in the mixture is 565 mmHg and the partial pressure of the oxygen is 1.55 atm, what is the total pressure of the mixture in kPa?
We must convert the pressure of cyclopropane and oxygen into the kPa. We can use the proportion to find the pressure in kPa. The pressure of cyclopropane will be: 760mmHg/565mmHg = 101.325kPa/x; x = 75.327kPa. The pressure of oxygen will be: 1atm/1.55atm = 101.325kPa/x; x = 157.05375kPa. The total pressure will be 75.327+157.05375 = 232.38075kPa.
