Over the years, the thermite reaction has been used for welding railroad rails, in incendiary bombs, and to ignite solid-fuel rocket motors. The reaction is given below.
You need to convert everything into moles, and then look at the stochiomietry of your reaction. Note I am using rough M.W. so if you want to be more exact, use the exact values from the periodic table.
Then, this means that you'll need 0.462mol/2 = 0.231 mole of Iron Oxide, and 0.462 mol of Aluminum.
Al = about 26 g/mol, so you need 12.012 grams.
Hope this helps. Check my math.
