Problems with conversion
« on: January 16, 2006, 07:25:07 PM »
I recently signed up for a general chem course at the undergrad level.  I have had chem before, but it's been four years!

I was given a so-called "review" problem, and I can't seem to figure it out.  Can someone help me?

The Ideal Gas Law is PV=nRT, of course.  If:

P=1.00 atm
V=22.4L
n-1.00 mol
and T=273K

What is the value of R in correct sig figs?

If anyone would be willing to help me with this, I would appreciate you guys explaining to me how you got the answer . . . how do you convert to common units?  Or do you even have to do this with this problem?

HELP ME PLEASE!

atm, mol, L and K are as good units as every other, so no need for conversion, unless you are asked to express R in some specific units other than given. If not, just combine numbers you have - and don't forget how many SD you are allowed to use for these data.
