STP is 101.325 kP and 0C.

1) P1V!/T1 = P2V2/T2

101.325*V1/273.15 = 1.52*94.4/296.15

V1 = 273.15*1.52*94.4/(101.325*296.15 = 1.306 dm^3 = 1.31 dm^3 to 3 significant figures

2)

101.325*V1/273.15 = 104.2*2280/303.15

V1 = 273.15*104.2*2280/(303.15*101.325)

V1 = 2113 cm^3 = 2110 cm^3 to 3 significant figures
