I solved this qs and got overall dh in kj / mole but when i put it in formula dh =du +dnrt... dh term is in kj / mole and dnrt term in kj after solving it..

the term dnRT gives you quantity with unit Kj while the dH you got with given data is in KJ/mole.. you cannot subtract two different quantities.. plz check you did wrong

if im doing conversion answer is not coming..

see by doing conversion my answer is not coming
