Question

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?

Answer 1

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

Step-by-step 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 =
`16g* 2=32g`

In formation of
`SO_2` , 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.
