Today there is a thing called 4-chlorocinnamic acid (4-chlorocinnamic acid), and we want to know its molecular weight (Molecular Weight). This is an urgent task and needs to be investigated in detail. Covering molecular weights is crucial in various chemical studies and practical applications.

Or based on chemical principles, analyze its molecular composition and calculate it accurately according to the relative atomic mass of each atom. The molecule of 4-chlorocinnamic acid is composed of carbon, hydrogen, chlorine, oxygen and other atoms. For carbon, the relative atomic mass is about 12; for hydrogen, about 1; for chlorine, about 35.5; for oxygen, about 16.

Examine its molecular structure in detail, count the number of atoms in detail, multiply the relative atomic mass of each atom by its atomic number according to arithmetic, and then add it up. In this way, the molecular weight of 4-chlorocinnamic acid may be obtained. This process requires careful and rigorous, and no error can be made to obtain accurate results to meet the needs.
