Respuesta :

To get the answer, you must know first the formula:


We know that moles = mass divided by molecular weight


So to get the mass, we need to alter the original formula, so


mass of sodium = 1.5 moles x atomic weight of Na


so what is the atomic weight of Sodium? It is 22.989769 u.


so the mass of sodium = 1.5 moles x 22.989769 u = 34.4846535
