Question

The no. Of atoms present in 4.4 g of co2is approx how much

Answer 1

We Know That,

n(Number of moles)= (Given mass/Molar mass)

                                =(No.of molecules present in Element or compound/

                                    Avogadro's Constant)

   Therefore, Molar Mass of CO₂=44

             4.4/44=n/6.022×10²³

             n=6.022×10²²
