Sulfur reacts with oxygen and creates two compounds. Compound A contains 1.34 g of sulfur for every 0.86 g of oxygen. Compound B

spayn [35]

Answer:

The mass ratio of oxygen rounded to the nearest whole no. 3 : 2

Explanation:

According to Law of Multiple proportion when two elements combine to make two or more different compounds, the mass ratio of the two element in the first compound, when divided by the mass ratio of the second compound , form a simple whole number ratio.

Compound A contains 1.34 g of sulfur for every 0.86 g of oxygen

$\frac{1.34}{0.86}= 1.5$

Compound B contains 11.63 g of sulfur for every 10.49 g of oxygen

$\frac{11.643}{10.49}= 1.0$

Ratio of oxygen in each compound

always put the larger number over the smaller number.

$\frac{CompoundA}{Compound B}=\frac{1.5}{1.0}=\frac{3}{2}$
