Answer:
given- molecular weight of CO2 -44g
given weight-8.80g
Explanation:
No of molecules=given weight/molecular unit
=8.80/44
=0.2moles
No of molecules=No of moles×N°
{N°=Avagqdro no=6.022×10raise to power23}
=0.2×6.02210power23
=1.2044×10power23
therefore 8.80g of CO2 contains 1.2044×10power23
of molecules of CO2
