Question

Calculate the relative molecular mass of water { H²O}​

Answer 1

Explanation:

$\huge\underline\purple{\mathfrak</p><p>Your Answer}$

⭐ Atomic mass of Hydrogen= 1u

Atomic mass of Oxygen= 16u

So, the molecular mass of water , which contains two atom of Hydrogen and one atom of oxygen is = 2*1+ 1*16

=> 18u

Answer 2

H2O

Water

Hydrogen atoms = 2

Hydrogen molecular mass = 2×1 = 2u

Oxygen atoms = 1

Oxygen molecular mass = 16×1 = 16u

Total molecular mass of water = 16u + 2u = 18u

18u ✔✔
