<em>m Al₂S₃: 27g×2 + 32g×3 = 150 g/mol</em>

150 g/mol  Al₂S₃ ==>> 2 moles of Al ==>> 12,04·10²³ atoms of Al
--------------------------------------
150g ------- 12,04·10²³  Al
3,28g ------ X 
X = (3,28×12,04·10²³)/<span>150g
</span>X = 0,2633·10²³ = <u>2,633</u><span><u>·10²</u></span><u>²  aluminium atoms</u>
