no.of molecules in 44g ofCO2=6.022×10^23
no.of molecules in 22g of CO2=6.022×10^23×44/22=6.022×10^23×2=12.044×10^23= 1.2044×10^24 molecules

Atomic mass of C-12g
Atomic mass of O-16g
molecular mass od CO2-12+2*16=12+32=44g
Now,1 mole of CO2 contain-44g
also,44g of CO2 contain - 6.022×10^23 molecules
hence, 1g of CO 2 contain-6.022×10^23/44
hence,22g of CO2 contain- 22*6.022*10^23/44=3.022*10^23
