pls answer the question

Answer 1

Hi friend ✋✋✋✋
---------------
Your answer
--------------------

Molecular mad of CO2 = [ 12 + (2 × 16) ] u = [12 + 32] u = 44 u

So,
------

Number of molecules in 44 grams of CO2 = 6.022 × 10²³

Number of molecules in 1 gram of CO2 = (6.022 × 10²³)/44

Number of molecules in 5.5 grams of CO2 = (6.022 × 10²³ × 5.5)/44

= 75.275 × 10^20

HOPE IT HELPS

Answer 2

1 atom of carbon has 6 × 10 ^23 molecules
5.5 atom of Co2 has 5.5 × 6 × 10 ^ 23
5.5 atom of carbon has 3.3 × 10^24 molecules 

Plz mark brainliest if right
