Answer to Question #119753 in Chemistry for aljoc

Question

Hydrogen gas in a closed container exerts a pressure of 84kPa. Determine the pressure in atmospheres

Answer 1

In order to determine the pressure in atmospheres, you must use a conversion factor. 1 atm equals 101325 Pa. 84 kPa is 84000 Pa:

$p(atm) = \frac{p(Pa)}{101325} = \frac{84000}{101325} = 0.83$ atm.

Answer: the pressure of hydrogen is 0.83 atm.
