Here is how the Percent Excess Oxygen equation looks like.

21 = (\frac{0.21 \cdot (10 - 5)}{5}) \cdot 100

21 = (\frac{0.21 \cdot (10mol - 5mol)}{5mol}) \cdot 100

21 = (\frac{0.21 \cdot (10 - 5)}{5}) \cdot 100

Percent Excess Oxygen Solution

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

FIRST Step Consider the formula

% Excess O 2 = (\frac{0.21 \cdot (M Fed - M OxyTheo)}{M OxyTheo}) \cdot 100

Next Step Substitute values of Variables

∴

% Excess O 2 = (\frac{0.21 \cdot (10mol - 5mol)}{5mol}) \cdot 100

Next Step Prepare to Evaluate

∴

% Excess O 2 = (\frac{0.21 \cdot (10 - 5)}{5}) \cdot 100

LAST Step Evaluate

∴

% Excess O 2 = 21
