What is the molar mass of water (H2O)?

What is the molar mass of water (H2O)?
A. 18 g/mol
B. 22 g/mol
C. 16 g/mol
D. 12 g/mol

Correct Option: Answer is A
The molar mass of a molecule is the sum of the atomic masses of its constituent atoms.
In a water molecule (H2O), there are two hydrogen atoms (H) and one oxygen atom (O).
The atomic mass of hydrogen is approximately 1.008 g/mol and that of oxygen is approximately 15.999 g/mol.
Therefore, the molar mass of water can be calculated as:
2 (H) * 1.008 g/mol + (O) * 15.999 g/mol ≈ 2.016 g/mol + 15.999 g/mol ≈ 18.015 g/mol
