What is the Combustion Analysis Calculator & How does it work?
Combustion analysis is a technique used to determine the empirical formula of an organic compound by burning it in excess oxygen and analyzing the products, typically carbon dioxide (CO₂) and water (H₂O). This calculator helps chemists quickly determine the composition of unknown compounds based on their combustion data.
The process involves measuring the mass of the sample before and after combustion to find the mass of CO₂ and H₂O produced. From these masses, you can calculate the moles of carbon (C) and hydrogen (H) in the compound. The remaining mass is assumed to be oxygen (O).

n_C = \frac{m_{CO₂} \times M_C}{M_{CO₂}}\
n_C = moles of carbon, m_{CO₂} = mass of CO₂, M_C = molar mass of C (12.01 g/mol), M_{CO₂} = molar mass of CO₂ (44.01 g/mol)
