Question

calculate co2 molecule in 0.22gm ​

Answer 1

Answer:

The answer is:-

Explanation:

Molecular mass of co2=44gm

no. of moles(n) =given mass/molecular mass

n=22/44=1/2

1 mole contains 6.022×10^23 molecules

1/2 moles contains (6.022×10^23)/2molecules

=3.011×10^23molecules

Answer 2

Answer:

3.011×10^21

Explanation:

no.of moles = 0.22/44 =0.005

no.of molecules = 0.005× 6.022×10^23

                           =3.011×10^21
