Consider 70.0-g samples of two different compounds consisting of only sulfur and oxygen. One of the compounds consists of 35.0 g of sulfur, and the other has 28.0 g of sulfur. Determine the ratio in whole numbers of the masses of sulfur that combine with 1.00 g of oxygen between the two compounds.

1 : 1.5

Explanation:

First Sample;

Ratio of sulfur and Oxygen

Mass of sulfur : Mass of oxygen

Mass of oxygen = Mass of sample - Mass of sulfur = 70 - 35 = 35g

35g : 35g

1 : 1

Second Sample;

Ratio of sulfur and Oxygen

Mass of sulfur : Mass of oxygen

Mass of oxygen = Mass of sample - Mass of sulfur = 70 - 28 = 42g

28g : 42g

1 : 1.5

Further reducing it to make oxygen 1;

0.6667 : 1

ratio in whole numbers of the masses of sulfur that combine with 1.00 g of oxygen between the two compounds;

0.6667 : 1

1 : 1.5
