5PRACTICE PROBLEM
A student in a chemistry lab prepared three different compounds containing only sulfur and oxygen. She then calculated the mass of each element in each of the compounds.
If the mass of oxygen in each compound per unit mass of sulfur is determined, and integer relationships are obtained, do the obtained numbers support the atomic theory?

ANSWERS OPTIONS
A
The integral ratios here indicate that oxygen atoms that combine with sulfur atoms are indivisible entities.
B
The non-integral ratios here indicate that oxygen atoms that combine with sulfur atoms are not indivisible entities.
