Conversions of Gases

Question

Convert 765 mmHg to atm, Pa, and kPa.

Answer 1

First we will need conversion factors:

1 atm = 760 mmHg

1 atm = 101,325 Pa

1000 Pa = 1 kPa

Now we will use dimensional analysis to convert from 765 mmHGg to atm, Pa, and kPa

765 mmHg (1 atm/760 mmHg) = 1.01 atm

1.01 atm (101,325 Pa/1 atm) = 102338 Pa

102338 Pa (1 kPa/ 1000 Pa) = 102.338 kPa
