Question

What is standard atmospheric pressure (760 mmHg) in inches mercury (in Hg)? (2.54 cm = 1 in)

science chemistry

Answer 1

Answer #1

1 mm Hg = 0.03937023 in Hg. Then

760 mmHg = 760 × 0.03937023

= 29.921373 in Hg

760 mmHg = 29.921373 in Hg

The column of a mercury barometer is calibrated in linear units (such as inches or millimeters) and thus the air pressure observed on such a barometer is reported in terms of these linear units. This measurement of pressure can be converted to other common pressure units. Some conversion factors are shown here. 1mm Hg = 1torr 1 atm = 760mm Hg 1 atm = 1.01325 bar 1 Pa = 10-5 bar 1 in = 2.54 cm 1 cm = 10...
