Carbon Yield Formula:
From: | To: |
Definition: This calculator determines the percentage yield of carbon in an organic compound based on the mass of CO2 formed during combustion.
Purpose: It helps chemists and researchers analyze the carbon content in organic compounds through combustion analysis.
The calculator uses the formula:
Where:
Explanation: The formula calculates what percentage of the original compound's mass was carbon by measuring the CO2 produced.
Details: Accurate carbon percentage determination is crucial for understanding molecular composition, purity analysis, and empirical formula determination.
Tips: Enter the mass of CO2 formed (in kg) and the original mass of the organic compound (in kg). Both values must be > 0.
Q1: Why is the ratio 12/44 used?
A: This represents the mass fraction of carbon in CO2 (12 g/mol C ÷ 44 g/mol CO2).
Q2: What units should I use for mass?
A: The calculator uses kilograms, but any consistent mass unit can be used as the units cancel out in the ratio.
Q3: Does this work for all organic compounds?
A: Yes, as long as complete combustion occurs and all carbon converts to CO2.
Q4: What if other elements are present?
A: This calculation only determines carbon content. Separate analyses are needed for other elements.
Q5: How accurate is this method?
A: Very accurate when performed correctly, typically within 0.1-0.5% of actual values.
