Question

The diagram shows the molecular structure of water. A diagram representing a molecule of water is shown. There is an O at the top with an H branching to its left and another H branching to its right. The ratio of hydrogen atoms to oxygen atoms in water is always the same. How many oxygen atoms (O) are there when there are 8 hydrogen atoms (H)? Enter the correct answer in the box. oxygen atoms

Answer 1

By using ratio, it is obtained that if there are 8 atoms of hydrogen, there are 4 atoms of oxygen.

What is ratio?

Ratio is used to find a comparision between two quantities with the same unit

The first part of the ratio is called antecedant and the second part of the ratio is called consequent.

Here,

In a molecule of water, there are 2 atoms of hydrogen and 1 atom of oxygen

Ratio of hydrogen and oxygen = 2 : 1

Number of atoms of hydrogen = 8

Let the number of hydrogen atom be 2x and number of oxygen atom be x

By the problem,

$2x = 8\\x = \frac{8}{2}\\x = 4$

Number of oxygen atom = 4
