FREE Expert Solution

We’re being asked to find the pressure in torr from inches of Hg (or in Hg). The given pressure in 30.47 in Hg (or inches of Hg). 

We’re going to convert mm Hg to in Hg:

mm Hg → m Hg → cm Hg → in Hg        

Hg does not change so we can do the conversion as:

mm → m → cm → in
