corrected boiling point of liquids?
« on: January 10, 2013, 12:02:15 PM »
A liquid boils at 102.5 degrees Celsius in a lab where the ambient pressure is 742 torr. What is the corrected (normal) boiling point?

I started this problem by doing: 760 - 742 = 18
then I read somewhere that you can estimate 0.35 degrees Celsius for every 10 torr difference?
Is that correct?
so I multiplied 0.8 * 35 = 28 and added this to 102.5 and got 130.5 for the normal boiling point. I feel like my answer is wrong. HELP PLS

0.35 degrees Celsius for every 10 tor
How many degrees Celsius for 18 tor

Can't be more than a degree. Your arithmetic's wrong.
