**DrBob222**, Friday, December 3, 2010 at 7:45pmTwo ways to do it.

Use PV = nRT for the first set of conditions and solve for n, then redo PV = nRT, use the n from above and the new conditions, and solve for pressure.

Second way is to use

(P1V1/T1) = (P2V2/T2)

The second way is a little shorter since you cut out the solving for n step.

**Sue**, Saturday, December 4, 2010 at 10:22amThanks! I knew the formula but wasn't quite sure if i convert mL to L in the formula. I know that I must covert C to K and Torr to Atm for the equation.
