Question

the volume at s.t.p occupied by a gas Y originally occupying 760cc at 300k and 70cm.press of Hg

calculate

Answer 1

76 cm hg= 1 ATM pressure

At STP T=273 V=22400 cm^3

Thus PV=NRT OR NR=CONSTANT=PV/T OR V/T= CONSTANT.

300/300=V/273or V=273 cm^3

Answer 2

ANSWER
.......


➡️ ➡️ ➡️ ➡️ ➡️ ➡️ ➡️ ➡️ ➡️

76 CM HG = 1 ATM PRESSURES
...

T = 273
V = 22400 CM ^ 3


....


PV = NRT
...

300 / 300
..
V = 273 CM ^3
