Theoretical Yield from 1 g Reagent Producing Heavy Product

Converting 1 g of a 10 g/mol reagent to a 200 g/mol product in a 1:1 reaction gives a theoretical yield of 20 g.

How to use this tool

  1. Enter mass of limiting reagent, molar mass of limiting reagent, molar mass of product and stoichiometric ratio (mol product / mol reagent) in the fields above.
  2. Results update instantly as you type — or click Calculate.
  3. Read your theoretical yield and the full breakdown beneath it.

See how a small-mass, low-molar-mass reagent can theoretically produce a much larger mass of a heavy product.

Frequently asked questions

What is a limiting reagent?
The reactant that is completely consumed first, limiting how much product can form. Any remaining reactant is in excess.
Where do I find the stoichiometric ratio?
From the balanced chemical equation. E.g. 2H₂ + O₂ → 2H₂O means 2 mol H₂ produces 2 mol H₂O, so ratio = 1:1. N₂ + 3H₂ → 2NH₃ means 1 mol N₂ → 2 mol NH₃, ratio = 2.
