Substances A and B are colourless gases obtained by combining sulfur and oxygen. Substance A results from combining 6.00g of sulfur with 5.99g of oxygen, and Substance B results from combining 8.60g of sulfur with 12.88g of oxygen. Show that the mass ratios in the two substances are simple multiples of each other.
How would I get started on this question the part that confuses me is the mass ratio. Any little Hints would be appreciated.
