Chemistry

Combustion Analysis Calculator is a chemistry calculator that helps you calculate combustion analysis values from your input data. The formula used is: n_C = m_CO2 / 44.01, n_H = 2 * m_H2O / 18.015, Empirical formula from molar ratios. Uses standard SI and chemistry units (mol, L, g/mol, M, Pa, K) unless otherwise stated.

Formula

n_C = m_CO2 / 44.01, n_H = 2 * m_H2O / 18.015, Empirical formula from molar ratios
  • Combustion Analysis Calculator gives you a fast estimate using your inputs and updates instantly when you change any value.
  • Formula: n_C = m_CO2 / 44.01, n_H = 2 * m_H2O / 18.015, Empirical formula from molar ratios
  • Input definitions: • Mass of CO2 produced: the numeric mass of co2 produced used in the calculation • Mass of H2O produced: the numeric mass of h2o produced used in the calculation • Mass of original compound: the numeric mass of original compound used in the calculation
  • Manual method: write down each input, apply the formula step by step, then compare your manual result with the calculator output.
  • Uses standard SI and chemistry units (mol, L, g/mol, M, Pa, K) unless otherwise stated.
  • Based on standard stoichiometric and thermodynamic equations. Results may vary with temperature, pressure, and substance purity.
  • Cross-check results against known standards or reference tables to confirm they are physically reasonable.
  • Practical tip: test a low, medium, and high scenario to understand sensitivity before making decisions.

Example Calculation

Inputs
  • Mass of CO2 produced: 4.4 g
  • Mass of H2O produced: 2.25 g
  • Mass of original compound: 3 g

Suppose you enter: Mass of CO2 produced = 4.4, Mass of H2O produced = 2.25, Mass of original compound = 3. The calculator applies the formula (n_C = m_CO2 / 44.01, n_H = 2 * m_H2O / 18.015, Empirical formula from molar ratios) and shows all output values below. Change any input field to immediately see how the result changes.
