A mole is defined as 6.02214076 × [tex]10^{23}[/tex] of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
[tex]Moles = \frac{mass}{molar \;mass}[/tex]
[tex]12.34 mol = \frac{mass}{342.14 g/mole.}[/tex]
[tex]Mass =12.34 mol x 342.14 g/mole[/tex]
= 4222.0076g
Hence, 4222.0076g is the mass of 12.34 mol of [tex]Al_2(SO_4)_3.[/tex]
