"On the Molecular Weight of Potassium Acetate"

The molecular weight of potassium acetate should be studied. Potassium acetate is composed of potassium, carbon, hydrogen, and oxygen.

The atomic weight of potassium is about 39.0983. In acetate, the atomic weight of carbon is about 12.0107, the atomic weight of hydrogen is about 1.00794, and the atomic weight of oxygen is about 15.9994. Acetate ($CH_3COO ^ - $) contains two carbon, three hydrogen, and two oxygen.

First calculate the formula weight of acetate, the amount of dicarbon is 2 dollars\ times12.0107 = 24.0214 $, the amount of trihydrogen is 3 dollars\ times1.00794 = 3.02382 $, the amount of dioxygen is 2 dollars\ times15.9994 = 31.9988 $, the formula weight of acetate is about 24.0214 dollars + 3.02382 + 31.9988 = 59.04402 $.

The atomic weight of recombined potassium, the molecular weight of potassium acetate is about 39.0983 dollars + 59.04402 = 98.14232 $.

From this point of view, the molecular weight of potassium acetate is the sum of the atomic weights of various elements according to their quantities in compounds. Knowing this principle is of great benefit to chemical research, experiments and applications.
