Answer to Question #118930 in General Chemistry for nicole

Question

Of the gases in the sample, 7800 mmHg is exerted by nitrogen, 2100 mmHg is exerted by oxygen, 93 mmHg is exerted by argon, and 4 mmHg is exerted by carbon dioxide. What is the total pressure of the gases in the sample? Using the GUESS method, what information should be used for U?

Answer 1

The total pressure of a mix of gasses in a certain volume equals the total of the partial pressures of the individual gasses added together. Algebraically. Total = argon(93) + carbon dioxide(4) + nitrogen(7800) + oxygen(2100) = 9997 mmHg
