**DrBob222**, Thursday, October 24, 2013 at 8:48pmUse PV = nRT.

P = 495 mm; convert to atm.

V = 585 mL; convert to L.

n = g/molar mass = 0.286/44 = ?

R = you know

T = kelvin. Substitute and solve for T in kelvin, the

K = 273 + C to calculate C.

**ellie**, Thursday, October 24, 2013 at 9:08pmWhen I've done the equation I've gotten 713.971 K for the first part. What have I done wrong?

**DrBob222**, Thursday, October 24, 2013 at 9:33pmProbably nothing. Using 44 for the molar mass of CO2 I obtained 714.3 K. You may have punched in a wrong digit somewhere.

For n I have 0.286/44 = 0.00650

Using 44.01 for the molar mass gave me 714.5 K.
