3.50 mol Al(NO3)3 reacts with 5.00 mols K2CrO4, the total number of moles of Al2(CrO4)3 and KNO3 would be?

Question

Here is the equation if it's needed.
2 Al(NO3)3(aq) + 3 K2CrO4(aq) → Al2(CrO4)3(s) + 6 KNO3(aq)

Answer 1

You do this the same way as the last one except this is a limiting reagent problem whereas the last one was not.
Use 3.50 mol Al(NO3)3 and determine mols KNO3.
Do it a second time with 5.00 mols K2CrO4 and calculate mols KNO3 formed.
It is likely the two answers will be different; the correct one in limiting reagent problems is ALWAYS the smaller value and the reagent producing that value is the limiting reagent.
