Post-Module Assess. #31 and #33

Postby Grace Lee 3G » Mon Nov 06, 2017 11:13 pm

For both questions: 2A + 1B ---> 3C

31. 1 mol B reacts with 2 mol A, but there is only 1 mol A present, so it is the limiting reagent.
How much of B would be used?

33. What is the maximum amount of product that can be produced?

Can someone please explain this to me?

31. Using the mole ratio provided in the chemical equation, 1 mole of A means that you'll use 0.5 moles of B. (You could convert this into grams if you know the grams per mole of B).

33. Since the limiting reagent is A, the max amount of product you could produce has to be calculated from the amount of limiting reagent you have. You would convert how many moles/grams of A you have using mole ratios to the moles/grams of the product.
