Homework Help: Chemistry

Posted by leo on Saturday, October 20, 2007 at 9:33pm.

A closed container is filled with oxygen. The pressure in the container is 435kPa . What is the pressure in millimeters of mercury?

(i know that 1atm=760mm Hg=101,325 Pa)

How do I use this to solve for the question? so: 435kPa*101,325=44,076,375Pa, & O2 = 32g/mol & you must have to use 760mmHg in there somehow, but then what.
The text really doesn't discuss this much, it only shows one sample prob which only gives a psi to convert to mmHg.

& how do you solve for pressure (in atmospheres) when given a msmt in "___cm's" -in a manometer- & given the atmospheric pressure in __atm?
