In the reaction below, how do you identify the limiting agent when 0.47 moles of Sodium are reacted with 26g of Copper(II) Nitrate?
#2Na(s) + Cu(NO_3)_2 -> 2NaNO_3 + Cu(s)#
The limiting reactant is
We know that we will need a balanced equation with masses, molar masses, and moles of the compounds involved.
1. Gather all the information in one place with molar masses above the formulas and everything else below the formulas.
2. Identify the limiting reactant
An easy way to identify the limiting reactant is to calculate the "moles of reaction" each will give:
You divide the moles of each reactant by its corresponding coefficient in the balanced equation.
I did that for you in the table above.
