<u>Answer:</u> The molar mass of water is 18 g/mol

<u>Explanation:</u>

Molar mass of a compound is defined as the sum of mass of every element each multiplied by the number of atoms of that element.

We are given a compound having chemical formula H_2O

Molar mass of hydrogen = 1 g/mol

Molar mass of oxygen = 16 g/mol

Mass of water = [(2\times 1)+16]=18g/mol

Hence, the molar mass of water is 18 g/mol
