Acommon anesthetic in dentistry known as nitronox consists of a mixture of dinitrogen oxide, n2o, and oxygen gas, o2, which is administered through an inhaler over the nose. if the anesthetic mixture has a total pressure of 740 mmhg, and the partial pressure of the oxygen is 370 mmhg, what is the partial pressure, in torr, of the dinitrogen oxide?

Anesthetic in dentistry  consists of a mixture of dinitrogen oxide (N₂O) and oxygen gas (O₂), which is administered through an inhaler over the nose. Total pressure of the mixture () is sum of partial pressure of N₂O () and partial pressure of O₂, ().

=370 mmHg

So, = (740-370) mmHg= 370 mmHg=370 torr

Hence, partial pressure of N₂O is 370 torr.

As, 1mmHg= 1 torr.
