I don't get this question..?

1 mole of an element contains 6.02 x 10^23 atoms and it has a mass of xx grams. For example, Al, in round numbers, is about 27 g for a mole; therefore, 27 g of Al contains 6.02 x 10^23 atoms.

So what do you think 27/6.02 x 10^23 = 4.48 x 10^-23 represents?

This is a trick question because the molar mass is the ratio of grams per mole and Avogadro’s number is the ratio of particles per mole,so dividing the molar mass of an element by Avogadro’s number yields the mass of a single representative particle of that element.Or in other words,What do you get by dividing the molar mass by Avogadro's number? The number of particles contain in the amount of that certain element.
