Percent Excess Air Solution

Follow our step by step solution on how to calculate Percent Excess Air?

FIRST Step Consider the formula

% Excess Air = (\frac{M Fed - M Theoretical}{M Theoretical}) \cdot 100

Next Step Substitute values of Variables

∴

% Excess Air = (\frac{10mol - 8mol}{8mol}) \cdot 100

Next Step Prepare to Evaluate

∴

% Excess Air = (\frac{10 - 8}{8}) \cdot 100

LAST Step Evaluate

∴

% Excess Air = 25
