Theoretical Yield vs Moles of Limiting Reagent
公式
## How to Calculate Theoretical Yield ### Formula **Yield = (moles_limiting × coeff_product / coeff_limiting) × Mw_product** First find moles of product from the mole ratio, then convert to grams.
计算示例
0.5 mol of C reacts (1:1 ratio) to produce CO2 (44.01 g/mol).
- 01Moles product = 0.5 × (1/1) = 0.5 mol
- 02Yield = 0.5 × 44.01 = 22.005 g
常见问题
What is theoretical yield?
The maximum amount of product that can be formed from the limiting reagent, assuming 100% conversion.
Why is actual yield usually less?
Side reactions, incomplete reactions, and losses during purification all reduce actual yield below theoretical.
How do I find the mole ratio?
From the balanced chemical equation, the coefficients give the mole ratio between reactants and products.
