**DrBob222**, Thursday, March 14, 2013 at 9:32pmI would do this the long way.

PV = nRT. We can ignore P and R since they are constants; therefore

V = nT

V = (12.0/32)*300 = about 112 but you do it more accurately.

Then 112/(273+81) = n = about 0.31

and 0.31 x 32 = about 10 g.

The short way is

(12/x) = (354/300)

x = 12 x (300/354) = ?

x =
