Answer to Question #205734 in General Chemistry for Sadie

Question

How many moles of copper(II) sulfate will react with 16.5 grams of

aluminum?

Answer 1

The balance chemical equation for the above is:

$2Al +3CuSO_4 \longrightarrow Al_2(SO_4)_3 +3Cu$

Moles of Aluminum $= \dfrac{16.5}{27} =0.6 moles$

Now by the mole mole analysis :

The moles of ,the moles of copper (ii) sulfate $= \dfrac{3}{2} \times 0.6=0.9 moles$
