2Al+3Cl2=2AlCl3
Please explain how you find the moles of this product.....I am totally confusing myself...

If that's all you're given, 2 is your best answer as it's the coefficient. However, if you have been given the number of moles of either of the reactants or if you have been given mass it may not be 2.
If you have been given the number of moles of, say, Al the number of moles will be the same as they have the same ratio (2:2), it you have been given the number of moles of Cl2 it will be that number x 2/3 (as the ratio is 3:2).
If you have been given a mass, use n=m/M (number of moles = mass divided by Molar mass) to find the number of moles of what you have been given the mass for, then (if it wasn't the product in question) do the step above.
Good luck!

The number of moles is the coefficient. The number in front of each compound is the number of moles needed for the reaction to happen at standard temperature and pressure. So there are 2 moles of AlCl3
