Question

what is the molecular formula of Co2​

Answer 1

o=c=o

i think you want to know the structure of Co2

Answer 2

⬇Molecular Formula of CO2⬇

Atomic mass of Carbon (C) = 12

Atomic mass of Oxygen (O2) = 16 × 2 = 32

Molecular mass of CO2 = Atomic mass of Carbon (C) + Atomic mass of Oxygen (O2)

Therefore, Molecular mass of CO2 = 12 + 32 = 44 amu

Structural formula of CO2⬇

O = C = O

This is a covalent bond. i.e, sharing of electrons between Oxygen and Carbon.
