Theoretical Yield Calculator

Find the theoretical yield of a product from reactant amounts, plus the limiting reactant and percent yield.

Open Theoretical Yield Calculator and you get an answer straight away, with no account to create. You will find it under Chemistry, with Percent yield calculator and Chemical Equation Balancer for the neighbouring cases.

How to use it

  1. Open the tool — no signup or install needed.
  2. Enter your input or adjust the available options.
  3. Get your result instantly, then copy or download it.

Frequently asked questions

What does Theoretical Yield Calculator do?

Find the theoretical yield of a product from reactant amounts, plus the limiting reactant and percent yield.

When would I actually use this?

Preparing a solution at a stated concentration, working out how much of a reagent a reaction needs, and converting between mass, moles and volume.

What is the most common mistake?

Confusing molarity with molality. One is per litre of solution and the other per kilogram of solvent; they diverge as concentration rises, and only one of them is temperature-independent.

How is Theoretical Yield Calculator different from Percent yield calculator?

They sit next to each other but answer different questions: Percent yield calculator is the one to open when you need it to compute the percent yield of a reaction from the actual and theoretical yield. Pick whichever matches what you're starting from — both are free.

Is there a tool for the next step?

Chemical Equation Balancer is the closest one after this: Balance any chemical equation instantly by solving the element matrix exactly — even tricky redox reactions.

What else is worth having open alongside it?

Empirical Formula Calculator and Limiting Reactant Calculator — they come up in the same task often enough to be worth a second tab.

Where do the figures come from?

Atomic masses are the IUPAC standard values. Results assume ideal behaviour and standard conditions unless the tool says otherwise — real solutions deviate, and lab work needs lab measurement.
