- Mass of limiting reagent = 10
- Molar mass of reagent = 58.44
- Moles of product per mole of reagent = 1
- Molar mass of product = 143.32
- Expected yield = 100
- Moles of reagent = 10 / 58.44 = 0.171 116
- Moles of product = 0.171 116 * 1 = 0.171 116
- Theoretical yield = 0.171 116 * 143.32 = 24.5243
- Yield at the stated efficiency = 24.5243 * 100 / 100 = 24.5243
Values are shown to six significant figures here; the arithmetic itself runs on exact fractions and is only rounded where a number is printed.

The formula
- moles of reagent = mass / molar mass
- moles of product = moles of reagent x stoichiometric ratio
- theoretical yield = moles of product x molar mass of product
