Which equivalence factor should you use to convert from 3.48 x 1018 atoms of mg to moles of mg?
(1 mol mg/1 atom mg)
(1 mol mg/3.48 x 1018 atoms mg)
(1 mol mg/6.02 x 1023 atoms mg)
(6.02 x 1023 atoms mg/1 mol mg)

The first fact you should know to solve a stoichiometric problem like this one is that, there are 6.02 x 10^23 particles (atoms or molecules) in 1 mole of a substance. 

Now, to know the equivalence factor, it is important to know a technique which cancels like units when they are placed diagonally. Hence, to find the moles Mg from atoms, the equivalence factor must have a numerator with units of moles and a denominator with units of atoms. In this case, atoms would be cancelled, leaving the moles.

Ithink that the use of creativity in the sciences entails that one produce something out of nothing or from another thing. with this, i think that the he wrote down his results as four parts of the atomic theory is the manifestation of the  creativity of john dalton.
