What is the mass of—

(b) 4 moles of aluminium atoms (Atomic mass of aluminium = 27)?

 

 

Answer

We know that,

Mass of 1 mole of a substance = Molar mass of that substance

 

(b) 4 moles of aluminium atoms 

Molar Mass of Aluminium = 27g

Mass of 1 mole Aluminium atoms = Molar mass of aluminium = 27g

Mass of 4 moles Aluminium atoms = 4 x  Molar mass of aluminium

                                                       = 4 x 27g

                                                       = 108g
