You are asked to convert between pressure units.
You are given a pressure value.
Use the relationship 1 atm = 760 mm Hg to convert between these pressure units.

722 mm Hg × $\frac{1\text{ atm}}{760\text{ mm Hg}}$ = 0.950 atm

Is your answer reasonable? The pressure, 722 mm Hg, is less than 760 mm Hg, which is the equivalent of 1 atm. Therefore, the pressure expressed in units of atmospheres should be less than 1 atm.
