A cyclopropane-oxygen mixture is used as an anesthetic. If the partial pressure of cyclopropane in the mixture is 330 mmHg and the partial pressure of the oxygen is 1.0 atm, what is the total pressure of the mixture in torr?
A)1.4 torr
B)760 torr
C)430 torr
D)1100 torr
E)330 torr

1 atm is equivalent to 760 mmHg (or torr). Therefore, the partial pressure of oxygen is 760 torr. Adding the partial pressures of cyclopropane (330 torr) and oxygen (760 torr) gives a total pressure of 1090 torr, which is closest to 1100 torr.
