Chapter 8: Q. 8.80 (page 283)

What is the total pressure, in millimeters of mercury, of a gas mixture containing argon gas at $0.25 a t m$ ,helium gas at $350 m m H g$ , and nitrogen gas at $360 t o r r$ ?

Short Answer

Expert verified

The total pressure of a gas mixture is $900 m m H g$ .

Step by step solution

Given Information

We have given the partial pressure of argon is $0.25 a t m$ , of helium is $350 m m H g$ and of nitrogen is $360 t o r r$ .

Simplify

Considering the given conditions

The partial pressure of argon $P_{A r} = 0.25 a t m = (0.25 \times 760) m m H g = 190 m m H g$ ,

the partial pressure of helium $P_{H e} = 350 m m H g$

and the partial pressure of nitrogen role="math" localid="1652688858358" $P_{N} = 360 t o r r = 360 m m H g$ .

Dalton's law states that the sum partial pressure of the gasses in the mixture is the total pressure of the gas.

So, total pressure is

$P_{t o t a l} = P_{A r} + P_{H e} + P_{N} P_{t o t a l} = 190 m m H g + 350 m m H g + 360 m m H g P_{t o t a l} = 900 m m H g$
