which is the molar mass of h2o?\no 10.02 g/mol\no 16.00 g/mol\no 17.01 g/mol\no 18.02 g/mol

Explanation:

Step1: Identify atomic masses

The atomic mass of hydrogen (H) is approximately 1.01 g/mol and oxygen (O) is approximately 16.00 g/mol.

Step2: Calculate molar mass of H₂O

There are 2 hydrogen atoms and 1 oxygen atom in H₂O. So molar mass $M = 2\times1.01+16.00$. $M=2.02 + 16.00=18.02$ g/mol.

Answer:

18.02 g/mol
