what is the molar mass of aluminum?

Question

what is the  molar mass of aluminum?

Answer 1

Hi Sophie,

 

I don't think that this is so bad a question. If you look at the periodic table, you can see that Aluminum is the 13th element. It should say an Atomic Mass next to it, which is usually in grams. For Al, I read this to be 26.9815 g. This is the mass that a mole of aluminum has. The mass of a mole of Aluminum is called the molar mass. Remember, that a mole is 6.02 X 10²³ or something, so the molar mass of aluminum is the mass of 6.02 X 10²³, or Avagadro's number, of Al atoms.
