In: Chemistry

What volume of air will be expelled from a vessel containing 400 cm3 at 7°C when it is heated to 27° C at the same pressure ?

we have to solve this question using gas laws.

Expert Solution

I have used the Charles law, which is one of the gas laws and relates volume to the temperature of the gas.

 

we have 

Initial Volume:(Vi)=400 cm³

Initial Temperature:(Ti)=7°C = 273 +7 = 280K

Final Temperature:(Tf)=27°C = 300K 

we have to find the 

Final Volume: (Vf)=?

 

V1/T1=V2/T2

Vi/Ti=Vf/Tf

400/280=Vf/300

Vf=400*300/280

Vf=428.5

 

We need the volume of air expanded so

Vf-Vi=428.5-400

        =28.5cm³

 

        =28.5cm³

A mixture containing hydrogen and ammonia has a volume of 183.0 cm3 at 0.00 C and 1.0 atm. The mixture is cooled to the temperature of liquid nitrogen at which ammonia freezes out and the remaining gas is removed from the vessel. Upon warming the vessel to 0.00 C and 1 atm, the volume is 80.0 cm3. Using the ideal gas law, calculate the mole fraction of NH3 in the original mixture.
