The percent composition of methyl butanoate is 58.8% c, 9.8% h, and 31.4 % o and its molar mass is 102 g/mol. what is its empirical formula? what is its molecular formula?

a. a primary source combines several different accounts of an event. b. a primary source generally benefits from having been written after an event.

explanation:

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
