From the calculations, the amount of product formed is 3 moles of AlCl3
A chemical reaction is said to take place when two or more substances are combined to yield products.
The equation of the reaction is;
Al(NO3)3 + 3NaCl ------> 3NaNO3 + AlCl3
Given that 1 mole of Al(NO3)3 reacts with 3 moles of NaCl
x moles of Al(NO3)3 reacts with 9 mols of NaCl
x = 3 moles
This implies that NaCl is the limiting reactant.
If 3 moles of NaCl gives 1 moles of AlCl3
9 moles of NaCl gives 9 moles * 1 mole / 3 moles
= 3 moles of AlCl3
