Question

What is the total number of atoms found in one molecule of upper case H subscript 2 end subscript upper case O?

1
2
3
4

Answer 1

3 atoms are in H2O. Hydrogen, hydrogen, and oxygen.

Answer 2

Answer : The total number of atoms present in one molecule of
`H_2O` is, 3

Explanation :

Molecule : It is the smallest particle in the chemical compound or chemical element that has the same chemical properties of that compound or element.

The role of coefficient is important because coefficient tell us about that how many molecules or atoms present in the chemical equation.

The given molecule is,
`H_2O`

In this molecule, there are 2 number of hydrogen atoms and 1 number of oxygen atom.

Total number of atoms present in one molecule of
`H_2O` = 2 + 1 = 3

Thus, the total number of atoms present in one molecule of
`H_2O` is, 3
