Question

Diethyl ether (also known as “ether”), C4H10O (l), is an organic
compound that has long been used as a surgical anesthetic. The
complete combustion of 1 mol of C4H10O (l) to CO2 (g) and H2O (l) yields
ΔH °=-2723.7 kJ.
a) Write a balanced equation for the combustion of 1 mol of C4H10O
(l) to CO2 (g) and H2O (l)
b) Write a balanced equation for the formation of C4H10O (l) from its
elements.
c) By using the information in this problem and data in Table 5.3,
calculate ΔH f° for diethyl ether.

I got -3403 kJ for question c), is that correct?

Answer 1

My bad, I just corrected my answer and got -279.3 kJ
