We solve the quotient.......#"mass"/"molar mass"# to get the number of moles........

Explanation:

And so here.........we gets..........0.44⋅g44.01⋅g⋅mol−1=0.010⋅mol with respect to CO2.

But one mole specifies by definition, NA,Avogadro's number of molecules, where NA≡6.022×1023⋅mol−1.

And thus number of individual CO2 molecules is given by the product..6.022×1023⋅mol−1×0.010⋅mol≡6.022×1021 individual molecules of CO2. How many carbon atoms, and how many oxygen atoms does this molar quantity represent?
