Answer 2

Answer:

The given sentence is false.

Explanation:

The molecular mass of H2O:

Atomic mass of Hydrogen is 1.

Therefore, mass of two hydrogen is 2 × 1 = 2.

Now, atomic mass of oxygen is 16.

Therefore,

Molecular mass of H2O = Atomic mass of hydrogen + oxygen

=> 16 + 2 = 18

Therefore,

Molecular mass of H2O is 18.

The given sentence is false.
