assuming 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~ :)
thank you very much it does help a lot but when im doing this problems on my oown they dnt make any sense ..
