Question

The atmospheric pressure recorded was 29.08 in Hg. What is this pressure in torr?

Answer 1

You are basically being asked to convert inches of Hg to torr, which is the same as mm Hg. So, it boils down to converted inches to millimeters.

1 inch = 2.54 cm

1 cm = 10 mm

1 inch x 2.54 cm/inch x 10 mm/cm = 25.4 mm

29.08 inches Hg x 25.4 mm Hg/inch Hg = 738.6 mm Hg = 738.6 torr
