HELLO NADIA,
 The reaction is,
Al3+        +            3e-   ----------------------->   Al
1mole                    3mole                            1mole
1mole                     3faradays                      1 mole
 
1 mole of Al = 27gm is deposited by 3 faraday of electricity
therefore,
40.5gm of Al is deposited by = 3/27 X 40.5F
 
                                             = 3/27 X 40.5* 96500
                                             = 434250 Coulombs
