Question

The volume of asamplea saof nitrogen gas is 88mLat 25°C and 1.0 atm. Whatis its volume in LatSTP?V₁=88mL T₁=25°CV₂=? T₂=23°2

Answer 1

Given:

V1= 88 ml

P1= 1 atm

T1= 25°C= 298.15 K

STP conditions:

P2= 1atm

T2= 273.15 K

Apply :

`(P1V1)/(T1)=(P2V2)/(T2)`

Replacing:

`(1(88))/(298.15)=(1(V2))/(273.15)`
`88(273.15)=298.15V2`
`(88(273.15))/(298.15)=V2`

V2= 80.62 ml
