# Heat absorbtion equation?

How much heat is absorbed when 48g of O2 reacts completely with oxygen atoms according to this thermochemical equation? O(g) + O2(g)---> O3(g) Delta H deg = -106 kJ/mol

It seems simple, but I'm just not sure. I came out with -159kJ

Your answer is correct.

48 / 32 = 1.5 mol of O2

-106 times 1.5 = -159 kJ
