Question

What is the formula unit mas of CaCO3
(Calcium carbonate)

Answer 1

Formula unit mass of CaCO3 is

(1 x 40.0u) + (1 x 12.0 u) + (3 x 16.0u) = 100u

Answer 2

Hlo friend... Cutiepie Here..

Here is ur answer :

Formula unit mass :

The formula unit mass of a substance is the sum of the atomic masses of all atoms in a formula unit of a compound. The term 'formula unit' is used for those substances which are made up of ions.


Formula unit mass of CaCO3

Atomic mass of Ca = 40 u

Atomic mass of C = 12 u

Atomic mass of O = 16 u


CaCO3

➡️ 40 + 12 + 16 ×3

= 40 + 12 + 48

= 40 + 60

= 100u
