Answer : The total number of atoms present in one molecule of [tex]H_2O[/tex] 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, [tex]H_2O[/tex]
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 [tex]H_2O[/tex] = 2 + 1 = 3
Thus, the total number of atoms present in one molecule of [tex]H_2O[/tex] is, 3
