Question

A vessel at $987torr$ contains nitrogen, argon, helium, and carbon dioxide gases. The partial pressure of the first three gases are $44.0mmHg,466mmHg$, and $220mmHg$ respectively.
What is the partial pressure of carbon dioxide in atm?

• A. $1.30atm$
• B. $2.00atm$
• C. $0.338atm$
• D. $0.961atm$

Answer 1

The correct option is C $0.338atm$

Total pressure = sum of partial pressure.

Let Partial pressure of $C{O}_2=x987=44+466+220+xx=252torrx=0.338atm$

Ans: 0.338 atm
