Theoretical Yield Calculator

Find the maximum product mass from the limiting reactant.

Parameters Live Compute
Calculated Output
Theoretical yield 116.88
Product moles (mol) 2
Formula: yield = limiting moles × ratio × molar mass
Step-by-Step Breakdown
1. Values used:
2. Moles of limiting reactant = 2 mol
3. Product : reactant mole ratio = 1
4. Product molar mass = 58.44 g/mol
5.
6. Theoretical yield = Moles of limiting reactant x Product : reactant mole ratio x Product molar mass = 2 x 1 x 58.44 = 116.88
7. Product moles = Moles of limiting reactant x Product : reactant mole ratio = 2 x 1 = 2mol

The theoretical yield is the most product a reaction can produce.

The math behind it

product moles = limiting reactant moles × mole ratio; mass = moles × product molar mass.

Worked Example

2 mol, 1:1, 58.44 g/mol → 116.9 g.
