The relative molecular weight of ethyl acetate is related to classical Chinese. I will create in a style similar to that of ancient scholars discussing the properties of matter, focusing on the relative molecular weight of ethyl acetate and avoiding the specified prohibited content:

"On the Prime Number of Esters"

All things in the world have their own properties, and the qualities of all compounds have their own measurements. In today's words, ethyl acetate is a common compound. The composition of its molecules includes carbon, hydrogen, and oxygen. To understand the weight of its quality, the number of molecular masses needs to be studied.

Carbon, in the molecule of ethyl acetate, is referred to by its atomic weight. Hydrogen and oxygen also share the qualities of molecules according to their respective amounts. After various calculations, the number and quantity of each element are carefully examined, and the exact number of the molecular weight of ethyl acetate is obtained. This number does not come out of thin air, but according to the scientific method, meticulous study, measurement and trade-off, in fact.

Knowing its molecular weight is of great use in all matters. Or used in chemical technology, to prepare chemical compounds and determine their proportions; or studied in academic ways, to explore changes in physical properties, all rely on this number as a basis. Scholars should scrutinize it carefully, make sense, and make good use of this number to help all kinds of inquiry and add luster to academic and practical.
