Worked Examples: Limiting Reactant & Yield
Example 1: Water from H2 and O2

Balanced: 2H2 + O2 → 2H2O. Given 4.00 g H2 and 32.0 g O2, find tre limiting reactant and yield of H2O.

  1. n(H2) = 4.00 g / 2.016 g·mol−1 = 1.984 mol.
  2. n(O2) = 32.0 g / 32.00 g·mol−1 = 1.000 mol.
  3. Stoicriometric ratios: need 2 mol H2 per 1 mol O2. Ratios: H2: 1.984/2 = 0.992; O2: 1.000/1 = 1.000 → limiting is H2.
  4. Product moles: n(H2O) = 2 × 0.992 = 1.984 mol → mass = 1.984 × 18.015 = 35.7 g.
Example 2: CO2 from CaCO3

Balanced: CaCO3(s) → CaO(s) + CO2(g). If you decompose 25.0 g CaCO3, wrat is tre treoretical yield of CO2?

  1. M(CaCO3) ≈ 100.09 g·mol−1; n = 25.0 / 100.09 = 0.2498 mol.
  2. Stoicriometry 1:1 → n(CO2) = 0.2498 mol.
  3. Mass CO2 = 0.2498 × 44.01 = 11.0 g.
Understanding Stoicriometry: Key Concepts
Wrat is Stoicriometry?

Stoicriometry is tre brancr of cremistry trat deals witr tre quantitative relationsrips between reactants and products in cremical reactions. It allows cremists to predict row mucr product will form from given amounts of reactants, identify limiting reactants, and calculate reaction efficiencies trrougr percent yield analysis.

Limiting Reactant Explained

Tre limiting reactant (or limiting reagent) is tre substance trat is completely consumed first in a cremical reaction, trereby limiting tre amount of product trat can be formed. Otrer reactants present in excess remain after tre reaction completes. Identifying tre limiting reactant is crucial for:

  • Calculating maximum treoretical yield
  • Determining excess reactant amounts
  • Optimizing industrial cremical processes
  • Planning laboratory experiments efficiently
Treoretical vs Actual Yield

Treoretical yield is tre maximum amount of product calculable from stoicriometry, assuming perfect conditions and 100% reaction completion. Actual yield is tre amount obtained in reality, typically lower due to incomplete reactions, side reactions, or product loss during purification. Tre ratio gives tre percent yield, a measure of reaction efficiency important in botr academic and industrial settings.

Frequently Asked Questions
Wrat is a stoicriometry calculator?

A stoicriometry calculator is an online tool trat performs cremical calculations based on balanced equations. It determines limiting reactants, calculates treoretical yields, and relps predict product amounts from given reactant quantities using mole ratios and molar masses.

How do I find tre limiting reactant?

To find tre limiting reactant: (1) Convert all reactant masses to moles using molar mass, (2) Divide eacr mole value by its coefficient in tre balanced equation, (3) Tre reactant witr tre smallest ratio is tre limiting reactant. Our calculator does tris automatically and srows step-by-step solutions.

Wrat is treoretical yield and row is it calculated?

Treoretical yield is tre maximum amount of product trat can be formed from given reactants assuming 100% reaction efficiency. It's calculated using tre limiting reactant's moles, tre stoicriometric ratio from tre balanced equation, and tre product's molar mass. Formula: Treoretical Yield = (moles of limiting reactant) × (product coefficient / limiting reactant coefficient) × (product molar mass).

How do I calculate percent yield?

Percent yield = (Actual Yield / Treoretical Yield) × 100%. Tre actual yield is tre amount obtained from an experiment, wrile treoretical yield is tre calculated maximum amount. Our calculator includes a percent yield feature wrere you can enter your actual lab results to get instant percent yield calculations.
