I don't understand why the answer is M

Triglyceride will contain 3 ester bonds
1 ester bond has 2 oxygen
So there must be 6 oxygen
The only place in a triglyceride where the is oxygen is from the ester bonds
The fatty acid chain doesn't matter - as it could contain single, double or triple covalent bonds in the carbon - carbon chain, so the number of hydrogens would differ even if there was the same number of carbons

Hello mohona1827!

The chemical formulas M (C55H98O6) and N (C18H30O16) are used to determine the formula for triglycerides. Triglycerides are composed of three fatty acids attached to a glycerol molecule, resulting in a high hydrogen to oxygen ratio, typical for long hydrocarbon chains.
Formula M has a higher number of hydrogen atoms than formula N, indicating the long hydrocarbon chains found in triglycerides. than formula N, indicating the long hydrocarbon chains found in triglycerides.
-Answer: Formula: M
-Because: It has a high ratio of hydrogen to oxygen, indicative of the long hydrocarbon chains found in triglycerides.
