Question

sulfur and oxygen can react to form both sulfur dioxide and sulfur trioxide. in sulfur dioxide, there are 32.06 g. of sulfur and 32.00 g. of oxygen. in sulfur trioxide, 32.06 g. of sulfur are combined with 48.00 g. of oxygen.

a. what is the ratio of the weights of oxygen that combine with 32.06 g. of sulfur?

b.How do these data illustrate the law of multiple proportions?

Answer 1

"If two elements form more than one compound between them, then the ratios of the masses of the second element which combine with a fixed mass of the first element will be ratios of small whole numbers."

32/48 = 2/3
