Which will have greater volume when the following gases are compared at STP:
- 1.2/N2 at 25°C and 748 mmHg
- 1.25/O2 at STP
उत्तर
V = 1.2 litres
P = 748 mmHg
T = 298 K
P1 = 760 mmHg
T1 = 273 K
V1= ?
`("P" "V")/"T" = ("P"_1 "V"_1)/"T"_1`
`(748xx1.2)/298 = (760xx"V"_1)/273`
V1 = 1.081 litres
V = 1.25 litres
P = 760 mmHg
T = 273 K
P1 = 760 mmHg
T1 = 273 K
V1= ?
`("P" "V")/"T" = ("P"_1 "V"_1)/"T"_1`
`(760xx1.25)/273 = (760xx"V"_1)/273`
V1 = 1.25 litres
1.25 litres O2 will have a greater volume than 1.2 litres N2.
