Percent Excess Oxygen Solution

STEP 0: Pre-Calculation Summary

Formula Used

Percent Excess Oxygen = ((0.21*(Moles of Air Fed-Moles of Oxygen Theoretical))/Moles of Oxygen Theoretical)*100
% Excess O₂ = ((0.21*(M_Fed-M_OxyTheo))/M_OxyTheo)*100
This formula uses 3 Variables

Variables Used

Percent Excess Oxygen - Percent Excess Oxygen is the amount of oxygen in the incoming air not used during combustion and is related to percentage excess air.
Moles of Air Fed - (Measured in Mole) - Moles of Air Fed is defined as total moles of air that is being fed to the process for combustion.
Moles of Oxygen Theoretical - (Measured in Mole) - Moles of Oxygen Theoretical is the exact amount of Oxygen required for complete combustion.

STEP 1: Convert Input(s) to Base Unit

Moles of Air Fed: 10 Mole --> 10 Mole No Conversion Required
Moles of Oxygen Theoretical: 5 Mole --> 5 Mole No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

% Excess O₂ = ((0.21*(M_Fed-M_OxyTheo))/M_OxyTheo)*100 --> ((0.21*(10-5))/5)*100

Evaluating ... ...

% Excess O₂ = 21

STEP 3: Convert Result to Output's Unit

21 --> No Conversion Required

FINAL ANSWER

21 <-- Percent Excess Oxygen
