A vessel of volume 5 litres contain a gas at 5 atmospheres . The number of moles of the gas is 16. It is the connected to evacuated vessel of volume 3 litres . Assuming the temperature remains constant throughout th experiment the number of moles transferred to the other vessel is a ) 6 b ) 8 c ) 12 d ) 10

Answer»

Answer:

NSWER

By ideal gas EQUATION, PV = nRT

now we are given that T is constant

We observe that n α  PV

also number of MOLES depend on mass so number of moles will remain conserved

so, product PV will remain conserved because PV is proportional to "n"

so, P

 = 4 ltr

so, P
