Homework Answers
Percent yield is calculated by using the following formula :
Percent yield = (Experimental yield/Theoretical yield) × 100 %
In the given question, we need to calculate the percent yield of oxygen gas.
The calculated or theoretical yield of oxygen gas = 411 mL
The experimental yield of oxygen gas = 405 mL
Therefore using the formula of percent yield we get
Percent yield of oxygen gas = (Experimental yield of oxygen gas/Theoretical yield of oxygen gas) × 100%
= (405 mL/ 411 mL) × 100%
= (0.985) × 100%
= 98.5 %
