Verify the answer?
« on: November 07, 2011, 10:53:46 PM »
I keep getting conflicting answers on this one:

The total pressure of a sample of gas containing oxygen, nitrogen and argon is 1.00 atm. If the pressure..?
The total pressure of a sample of gas containing oxygen, nitrogen and argon is 1.00 atm. If the pressure of O2 is 160. mmHg and the pressure of N2 is 11.5 psi, what is the pressure of Ar?

A. 589 mmHg
B. 0.00700 atm
C. 7 x 10^-3 atm
D. 7 mmHg

Some say it's A, others say it's D. But I personally think it's B.

999-998 is not 1.00, it is 1. For 1.00 you need 999.00-998.00.
