Question

Answer 1

Answer #1

V = 215cm^3 = 215ml = 0.215L

T = 23.5+273 = 296.5K

P = 84.6KPa

experimental conditions STP conditions

V1 = 0.215L V2 =

T1 = 296.5K T2 = 273K

P1 = 84.6KPa P2 = 101.325KPa

P1V1/T1 = P2V2/T2

V2 = P1V1T2/T1P2

= 84.6*0.215*273/(296.5*101.325)

= 0.615L

volume of gas STP = 0.615L = 615cm^3
