Calculate H f for glycerin, C 3 H 8 O 3 , at 298 K using

Calculate ΔH^°_f for glycerin, C₃H₈O₃, at 298 K using the H found in Exercise 17.45.

Exercise 17.45

The products of the combustion reaction of glycerin, C₃H₈O₃, are gaseous carbon dioxide and liquid water. Write the balanced chemical equation for the combustion of 1 mol glycerin, and calculate ΔH for this reaction at 298 K if burning 1.240 g glycerin has a ΔE of -54.6 kJ.
