ClarityHow to use this tool
- Enter known reactant mass, reactant molar mass, reactant coefficient, product molar mass, product coefficient.
- Select Calculate to view the result.
- Check the method and assumptions below before using the result.
The method, explained
Product mass = reactant mass ÷ reactant molar mass × (product coefficient ÷ reactant coefficient) × product molar mass.
Using known reactant mass = 4.032 g, reactant molar mass = 2.016 g/mol, reactant coefficient = 2, product molar mass = 18.015 g/mol, product coefficient = 2, the result is 36.03 g product. Change these example inputs to match your task; use the method above to check each step.
Understanding your result
No. Enter coefficients from an already balanced equation. If two reactants are supplied in finite amounts, use Limiting Reactant first.
What to keep in mind
Requires a balanced reaction and enough of every other reactant. Assumes complete conversion and a pure starting material. Educational calculation only; use validated procedures for laboratory work.
