If 7 Ms and 4 N are given you to create moles. How many are able to be created? What are the excess and limiting reactants?

Question

Ms and N are fake elements in this scenario. It takes 2 Ms and 1 N to create a mole.

Answer 1

Once again, this is a ridiculous question, but at least part of it can be addressed.

One way to find the limiting and excess reactants are to divide the moles of each reactant by the coefficient in the balanced equation. Whichever value is less represents the LIMITING reactant. The other will be in excess.

7 Ms x 2Ms / mole = 3.5 moles of M can be created

4Ns x 1N / mole = 4 moles of N can be created

Since we don't know the balanced equation for the reaction of M + N, we can't determine the limiting reactant. If they react in a 1:1 mole ratio, then M would be limiting and N would be in excess.

Curious as to why your teacher doesn't give you REAL problems instead of making up these stupid examples that don't have answers.
