NEET Chemistry Atomic & Molecular Mass MCQ Question
What is the molecular mass of water (H2O) given that the atomic masses are approximately hydrogen = 1.008 u and oxygen = 16.00 u?
18.02 u
17.02 u
20.02 u
19.02 u
Correct Answer
Detailed Explanation
The molecular mass of water is calculated by adding the masses of its constituent atoms: 2 hydrogen atoms (2 x 1.008 u) and 1 oxygen atom (16.00 u), resulting in 18.02 u.
