A STP of a certain mass of gas occupies a volume of 800cm cube. find the temperature at which the gas occupies 940cm cube and has a pressure of 675mmhg

Answer 1

(P1V1/T1) = (P2V2/T2)
P1 = 760 mm Hg
V1 = 800 cc
T1 = 273 K
P2 = 675 mm Hg
V2 = 940 cc
T2 = ? K
T2 will be in degrees K. If you want degree celsius it will be
K = 273 + C.
