Question

What pressure in kilopascals and in atmospheres does a gas exert at 400 mm Hg?

Answer 1

a gas exerting a pressure of 400 mm Hg is equivalent to approximately 0.526 atm or 53.4 kPa.

Step-by-step explanation:

To convert 400 mm Hg to kilopascals or atmospheres, we can use the following conversion factors:

1 atm = 101.325 kPa

1 atm = 760 mm Hg

Therefore, we can first convert 400 mm Hg to atmospheres:

400 mm Hg * (1 atm / 760 mm Hg) = 0.526 atm

And then we can convert 0.526 atm to kilopascals:

0.526 atm * 101.325 kPa / atm = 53.4 kPa
