- Question
What does one mole of H2O correspond to
Options- A. 16 gms
- B. 18 gms
- C. 20 gms
- D. 22 gms
- Correct Answer
- 18 gms
ExplanationThe molar mass of H2O can be calculated as the following.
M(H2O)= [2 x M(H)] + [M(O)].
And we know that M(H) = 1g/mol, M(O) = 16g/mol.
So, M(H2O)= 2x1 + 16 = 18g/mol,
That means 1 mole of H2O contains 18g.
Hence, one mole of H2O corresponds to 18 grams.
