i cant answer this problem. help me! and also give solutions so i can understand... :
a given mass of He has a volume of 200mL. to what absolute temperature must it be treated to have a volume of 0.8L at 1.2 atm.?
(its related to gas laws like boyle's, charles ,gay-lussacs, combined gas law. ang please remember to use KELVIN because its an abs. temp. ok? {Kelvin=Celsius+273}. TY!)

well mr steve (first answerer) thats my problem the problem doesnt specify the other temperature. but ok i think its STP. but how about the pressure? its not in STP because 1.2 atm (not 1.0 atm which is at STP) BUT OK OK... IM not quite good at this... maybe there is some kind of other conversions or something?

OK I QUITE UNDERTAND...

You don't specify, but I suppose the original gas is at STP.
P1V1/T1 = P2V2/T2
T2 = P2V2T1/P1V1
T2 = (1.2atm)(800mL)(273K)/(1atm)(200mL) = 1310K

use formula-
v1/p1=v2/t2
so you would get then answer 277.8
