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

Explanation:

And so here.........we gets..........(0.44*g)/(44.01*g*mol^-1)=0.010*mol with respect to CO_2.

But one mole specifies by definition, N_A, "Avogadro's number" of molecules, where N_A-=6.022xx10^23*mol^-1.

And thus number of individual CO_2 molecules is given by the product..6.022xx10^23*mol^-1xx0.010*mol-=6.022xx10^21 individual molecules of CO_2. How many carbon atoms, and how many oxygen atoms does this molar quantity represent?
