Question

what is the no. of molecules if 44gm of CO2 present in 44gm of CO2​

Answer 1

Answer:

First we get and calculate the atomic weight of carbon and oxygen

Carbon = 12 and oxygen=16

CO2=12+(16×2)

=12+32

=44u

44gm of CO2 has 6.2×10^23 molecules (Avogadro's number)

Therefore, 44g=(44×6.2×10^23)/44

=6.2×10^23 molecules
