Question

What molar quantity is associated with a `0.44*g` mass of `"carbon dioxide"`?

Answer 1

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?
