You use the combined gas equation:
P1V1/T1 = P2V2/T2
Convert -140°C to K = 133K
Substitute:
5*200/133 = 1*V2/273
V2 = (5*200*273)/ 133
V2 = 273000/133
V2 = 2,052.6
New volume will be 2,053 litres

through fact the gas isn't given, i visit think of it quite is a suited gas; as such, you prefer to locate the quantity of the gas at STP. The equation to arise to now's PV/T = pv/t [the place the uppercase is venture a million and the lowercase is venture 2] in case you rearrange the above, you will get an equation like right here: PVt/Tp = v in case you remedy that equation, you will get the quantity of the gas at STP: 97kPA * 140mL * t / [ (273.15K + 35) * (p)] = v I even have not entered the values for STP through fact i don't be attentive to which STP values you're using. So basically remedy the above and you gets your answer.

STP is standard temperature and pressure. Standard temperature = 273.15K and Standard Pressure = 1 atm. The temperature is irrelevant while solving this. The equation for this is
P1V1 = P2V2 so (200L) (5atm) = (unknown volume) (1atm)
(1000L) = unknown volume
