What are common mistakes students make with limiting reagent problems?
Two common errors come to mind for me. Not converting amounts of reactants to moles and not using the coefficients from a balanced equation.
Let's consider the following reaction
We need to balance the equation to do any stoich work
If we have 6g of
6g of hydrogen is equal to 3 moles (the number from the balanced equation) of
14g of Nitrogen is only a half mole of diatomic nitrogen (
Using the coefficients from the balanced equation, we can conclude that if we only have 0.5mole
Here is a video to help further with this concept.
