Ayaan Heath · Answer 1

The volume of the gas that occupy at STP is 165. 28 cm^3

calculation

by use of combined gas law that is P1V1/T1=P2V2/T2, where

P1=84.6 kpa

T1=23.5 + 273=296.5 K

V1=215 cm^3

At STP T = 273 K and P = 101.325 Kpa

therefore p2 = 101.325 Kpa and T2 = 272 K V2=?

by making V2 the subject of the formula V2 = T2P1V1/P2T1

V2 = 273 K x 84.6 Kpa x 215 cm^3 / 101,.325 Kpa x296.5 K = 165.28 cm^3
