Question

calculate the mass of a molecule of Co2​

Answer 1

Answer:

1 mole CO2 contains 6.022×10^23 molecules of CO2. So, mass of 6.022 × 10^23 molecules = 44 g. Mass of one molecule of CO2 = 44/(6.022×10^23) g = 7.3 × 10^-23 g.

Answer 2

Answer:

As we know,

No. of molecules = No. of moles×Avogadro Number

No. of moles =Avogadro numberNo. of molecules​

Atomic Mass of C=12u

Atomic Mass of O=16u

Molecular Mass of CO2​=12+(2×16)=44 u

Mass of One molecule of CO2​=6.023×102344​

                                                      = 7.30×10−23
