Homework Help: chemistry

Posted by sarah on Monday, February 26, 2007 at 8:08am.

At 650 degree C and a pressure of 690mm HG, the 0.927g sample has a volume of 194cm3.

How do I calculate the volume at the same temp but at a pressure of 760mm Hg?

Also, how do I calculate the volume at the same pressure but at a temp of 0 degree C?

Thanks

if it is a gas, you can use the combined gas law.

P1V1/T1=P2v2/T2

change temsp to K.
