Live result84%unrecovered 1.6 g · 0.6 g below the 90% target
Formula used

Percent yield = actual yield ÷ theoretical yield × 100. Yield difference = actual yield − theoretical yield. Unrecovered amount = max(0, theoretical yield − actual yield). Target actual yield = theoretical yield × target yield percent ÷ 100.

This is the method behind the answer, so the result can be checked rather than simply trusted.

Assumptions used

What this answer assumes

Best for chemistry homework, lab notebooks, classroom examples, QA notes and production-learning records where actual and theoretical yield must stay visible beside the percentage.

  • Actual yield and theoretical yield must use the same unit and substance basis, such as grams of the purified product.
  • Theoretical yield is the denominator and must be greater than zero.
  • A percent yield above 100% can happen in real notes when the product is wet, impure, contaminated, weighed incorrectly or when the theoretical-yield setup is wrong.
  • The calculator performs arithmetic only; it does not validate stoichiometry, purity, limiting reactants, significant figures, lab safety or process compliance.
  • For graded lab reports, regulated production or safety decisions, follow the instructor, laboratory method, standard operating procedure or professional review.

Master’s Tip

How to use the result well

Master’s Tip: print the substance name, limiting-reactant note and whether the mass was dry or wet beside the percent yield. The arithmetic can look precise even when the product basis, purity or weighing step is the real source of error.

Method

Percent yield = actual yield ÷ theoretical yield × 100. Yield difference = actual yield − theoretical yield. Unrecovered amount = max(0, theoretical yield − actual yield). Target actual yield = theoretical yield × target yield percent ÷ 100.

  1. If the actual yield is 8.4 g and the theoretical yield is 10 g, percent yield = 8.4 ÷ 10 × 100 = 84.00%. The unrecovered amount is 1.6 g. Against a 90% target, the target actual yield would be 9.0 g, so the result is 0.6 g below target.

Assumptions

  • Actual yield and theoretical yield must use the same unit and substance basis, such as grams of the purified product.
  • Theoretical yield is the denominator and must be greater than zero.
  • A percent yield above 100% can happen in real notes when the product is wet, impure, contaminated, weighed incorrectly or when the theoretical-yield setup is wrong.
  • The calculator performs arithmetic only; it does not validate stoichiometry, purity, limiting reactants, significant figures, lab safety or process compliance.
