Express 798 mm Hg in units of atm

0.691 atm

I disagree with the above answer.

It should be 1 atm = 760 mm; therefore,
798 mm x (1 atm/760) = about 1.05 atm.

To express a pressure value in units of atm (atmospheres), you can use the conversion factor between mm Hg (millimeters of mercury) and atm. The conversion factor is 1 atm = 760 mm Hg.

To convert 798 mm Hg to atm, divide the value by the conversion factor:

798 mm Hg / 760 mm Hg/atm

Simplifying the expression:

798 / 760 atm

Now, perform the division:

798 / 760 ≈ 1.050 atm

Therefore, 798 mm Hg is approximately equal to 1.050 atm.
