Question

calculate the number of molecules prasent in 22gm of co2

Answer 1

First , find no. of moles

No. of moles = Given weight / molecular weight
= 22 / 44
= 1 / 2 = .5

Now. , no. of molecule in 1 mole = 6.02×10^23
no. of molecule in .5 mole = .5 × 6.02 ×10^23
= 3.01 × 10^23 molecule.

Answer 2

Heya user☺☺

Molar mass of CO2 =44g

And, 44g of CO2 = 1 mole of CO2 molecules

1g of CO2 = 1/44 mole molecules of CO2

So, 22g of CO2 = 1 /2 mole molecules of CO2

Since, 1 MOLE= 6.023 × 10^23.

1\2 mole CO2 = 3.0115 × 10^23 molecules of CO2.


Hope this will help
