**Jai**, Sunday, April 10, 2011 at 12:55amassuming the gas is ideal, we can use the formula,

P1*V1/T1 = P2*V2/T2

where

P1 = initial pressure

V1 = initial volume

T1 = initial temperature (in K)

P2 = final pressure

V2 = final volume

T2 = final temperature (in K)

we first convert the given temp to Kelvin units:

T2 = 12 + 273.15 = 285.15 K

*then note that at STP, temp is at 273.15 K and 1 atm. substituting,

P1*V1/T1 = P2*V2/T2

(1)(828) / 273.15 = (P2)(598) / 285.15

P2 = (828)(285.15) / (273.15)(598)

P2 = 1.45 atm

hope this helps~ :)
