Question

44 gram of CO2 contains ___ number of molecules

Answer 1

mass of CO2=44 gm

no of moles*Na=no of particles

Na=6.022*10^23

44/44*6.022*10^23

=6.022*10^23 particles

or

avogadro number of particles

Answer 2

Explanation:

relative molecular mass of co2 is 44.(O=16,C=12).so the number of atomsin 44g is 6.022×10^23(avegadro constant).therefore the number ofcarbon atoms in 22g is 6.022×10^23/2.as in one atom there is only one atom of carbon. There is onecarbon atom in each molecule ofCO2.
