Ans my question and explain it deeply with fundamental ideas.... ..
Dear Nilanjan A perfect gas equation is also known as an ideal gas equation.and we know , Ideal gas equation , PV = nRT where P = pressure V = volumen = number of moles R = universal gas constantT = temperature in KelvinGiven, weight of Hydrogen = 4g so, n = number of moles = given weight/molecular weight= 4g/2g = 2 Hence, perfect gas equation , PV = 2RT
Molecular weight of hydrogen is 2g.So 2 gm contains 1 mole of hydrogen.Therefore 4gm contains 4/2=2 mole hydrogen.Ideal gas equation is PV=nRT.Here n=2.so the eq becomes PV=2RT.Please approve if helped.
mole of hydrogen n = 4/2 = 2so from ideal gas equationPV = nRTPV = 2RTHope it clears...........................................................
