which is the molar mass of h2o? 10.02 g/mol 16.00 g/mol 17.01 g/mol 18.02 g/mol
Answer
Answer:
D. 18.02 g/mol
Explanation:
Step1: Identify atomic masses
Hydrogen (H) has an atomic mass of approximately 1.01 g/mol, and oxygen (O) has an atomic mass of approximately 16.00 g/mol.
Step2: Calculate molar mass of H₂O
The formula for water is H₂O. There are 2 hydrogen atoms and 1 oxygen atom. So the molar mass $M = 2\times1.01+ 1\times16.00$. $M=2.02 + 16.00=18.02$ g/mol.
