Problem

Compounds A and B are colorless gases obtained by combining sulfur with oxygen. Compound A results from combining 6.00g of sulfur with 5.99 g of oxygen, and compound B results from combining 8.60g of sulfur with 12.88 g of oxygen.

Show that the mass ratios in the two compounds are simple multiples of each other.

Solution

We’re being asked to show that the mass ratio of the two compounds is a simple multiple of each others.

According to the Law of Multiple Proportions, when two elements (A & B) form different compounds, the masses of element B that combine with 1 g of A are a ratio of whole numbers.


We will do the following steps to solve the problem:

Step 1: Determine the mass ratio in compound A

Step 2: Determine the mass ratio in compound B

Step 3: Compare the mass ratio
