A gas occupies 18.5L at stp. what volume will it occupy at 735 torr and 57°c?

The volume that will be occupied at 735 torr and 57 c is 23.12 L

calculation

At STP temperature=273 k and pressure=760 torr by use of combined gas formula

that is P1V1/T1 = P2V2/T2

where; P1 = 760 torr

T1 = 273 K

V1 = 18.5 L

P2 = 735 torr

T2 = 57+273 = 330 K

V2=?

by making V2 the formula of subject

V2 = T2P1V1/P2T1

V2 = [ (18.5L x 330 k x 760 torr) / (735 torr x 273 k) ] = 23.12 L
