Energy of n= 2 is -328.32 kj / mole
Energy of n= 3 is - 145.92kj / mole
So
E3 - E2 = - 145.92 - (-328.32)
= 182.4 kj / mole. ..
Hope it helps you ...Mark as brainlist plz PlzZ plz

To determine in kcal / mole decide value by 4.18
Ans will be 43.6 which is approximately correct....
madam -313.6/n2 in (k cal/mol) and solve them answer is 44.3
My ans was in kj / mole and this is also correct ....
kk
Is tarha tb krtai h jb 1 shell given ho jb 2 given h to 2no ki values isi farmulai se nikal kr minus krai gai ... jis tarha mene kiya ... and bus fark ye h merI values kj / mole me h.....
Mark as brainlist plz PlzZ ...
If you are satisfied
i konow jb 2 shell maine ab n2 me (n1)2-(n2)2 kr ke bhi solve kr sakte hh
