Answer #1

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 %
