Question

calculate the molecular mass of pure water​

Answer 1

Hey MATE!!!

Molecular weight of H => 1gm

Hence molecular weight of 2 H = > 2(1) = 2 gm.

Molecular weight of O => 16gm.

Hence molecular weight of

H2O => 16 + 2 = 18 gm.

Hope it helps :))

Answer 2

Answer:

18u

Explanation:

for H2O

molecular weight of Hydrogen is 1u whereas molecular weight of Oxygen is 16u

so molecular weight is

=1×2+16
