What was the percentage composition of the compound CW? To find out, first divide the weight, in grams, of element C by the weight of the compound CW. Why should you multiply that decimal fraction by 100 to find the percentage? How can you find the percentage of W in the same compound? Repeat the experiment, but prepare only about half as many molecules of the compound CW. ” Then decompose the compound into the elements C and W. What was the percentage composition of the compound? How do the results of these two experiments illustrate the law of constant proportions?

To explain what made an element pure, Dalton developed what has come to be known as the atomic theory. He proposed that all matter is made up of tiny, indivisible, indestructible particles called atoms. According to his theory, the atoms of any one element are identical to each other but different from the atoms of any other element. Atoms of different elements differ in weight.
