A tall column of gas (M = 0.029 kg/mol) is at 300 K and uniform $g = 9.8$ m/s². The pressure at the bottom is 1.00 atm and at the top it is 0.90 atm. Find the height of the column in metres, to the nearest metre. $R = 8.314$ J/(mol K).

Answer:

925.00

Solution:

$H = \frac{RT}{M g} ln \frac{P _{1}}{P _{2}} = \frac{8.314 ( 300 )}{0.029 ( 9.8 )} ln \frac{1.00}{0.90} = 8776 \times 0.10536 = 924.7$ m, so 925 m.
