Question

12.The molecular mass of water is​

Answer 1

Answer:

Water = H2O

Mass of 2 mole of H atom = 2×1 g/mol

Mass of 1 mole of O atom = 1×16 g/mol

On adding the above numbers, we get,

2×1 g/mol + 1×16 g/mol

= 2 g/mol + 16 g/mol

= 18 g/mol

Therefore, the required molecular mass of water is 18 g/mol.

Answer 2

Answer:

Explanation:

The molecular mass of water - 18.02 g/mol
