If 1 atom of sulfur combines with 2 atoms of oxygen to form sulfur dioxide, what is the ratio of mass of sulfur atom to mass of oxygen atom in sulfur dioxide?

The ratio of mass of sulfur atom to mass of oxygen atom in sulfur dioxide is 1: 1.

Explanation:

Law of constant proportion states that In a chemical substance the elements are always present in definite proportions by mass. This law is also known as 'Law of definite proportions '.

Mass of 1 atom of sulphur = 32 g

Mass of 1 atom of oxygen = 16 g

Mass of 2 atoms of oxygen =

In formation of , 1 atom of sulfur combines with 2 atoms of oxygen and thus the mass ratio will be 32: 32= 1:1 .

Thus the ratio of mass of sulfur atom to mass of oxygen atom in sulfur dioxide is 1: 1.

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
