Mole Ratio Calculation

The mole ratio between components in a chemical reaction is determined by their stoichiometric coefficients.

Mole Ratio (A : B) = coefficient_A : coefficient_B

For multiple components, simplify by dividing all coefficients by their greatest common divisor (GCD).

Simplified Ratios = coefficients ÷ GCD

Where:

  • coefficientₙ: Stoichiometric coefficient for the nth component in the balanced equation.
  • GCD: Greatest common divisor of all coefficients.

Usage Notes:

  • Coefficients are typically positive integers from the balanced equation.
  • Enter formulas for all relevant components (reactants and products).
  • Comparison reaction allows relative stoichiometry analysis.

FAQs (Frequently Asked Questions)

What is a mole ratio?

A mole ratio is the ratio of the number of moles of one substance to the number of moles of another substance in a chemical reaction, based on the stoichiometric coefficients.

How are mole ratios calculated?

Mole ratios are the ratios of the coefficients in a balanced chemical equation, often simplified by dividing by the GCD.

Why simplify ratios with GCD?

Simplifying provides the lowest whole-number ratios, making it easier to understand the relative proportions in the reaction.

What are stoichiometric coefficients?

Stoichiometric coefficients are the numbers in front of chemical formulas in a balanced equation, indicating the relative number of moles.

Where can I find balanced equations?

Balanced chemical equations are derived from chemical reactions and can be found in textbooks, lab manuals, or online chemistry resources.
