Step one; calculate the number of of molecules are that are present in 2.78 moles using the avorgadros laws

That is from avorgadros law

1moles = 6.023 x10^23molecules what about 2.78mole = how many moles

=2.78molesx6.023 x10^23/1moles = 1.673 x10^24

dinide by 1000 to convert to KJ

that is 1.673 x10^24/1000=1.6735 x10^21kj
