Boyles Law Problem 2
« on: March 05, 2008, 10:47:05 PM »
A gas with a volume of 299 mL at 112 kPa changes to standard pressure. What will the new volume be?

My solution:
V2 = 112 x 299 /101.3 = 330.58 mL

Is this correct? Thank you.

All three Boyles Laws that you posted look correct at a quick glance. I think you got it.

How old is the book, or how up-to-date is your answer?

I think STP is now 100 kPa (http://en.wikipedia.org/w/index.php?title=Standard_conditions_for_temperature_and_pressure&oldid=195423994), but this may depend on your definition of STP, bizarrely enough...

Assuming RT or STP 25 ÂșC.  P = 101.325 kpa is suitable for this application
