In a lab, 33 g of potassium chloride is formed from 60.0 g of potassium chlorate decomposing. Calculate the theoretical yield and percent yield for this experiment.

The theoretical yield and percent yield for this experiment are 40 g and 82% respectively.

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number of particles.

To calculate the moles:

According to stochiometry:

2 moles of produce = 2 moles of

0.54 moles of should produce = of

Thus theoretical yield is

But Experimental yield is 33 g.

The theoretical yield and percent yield for this experiment are 40 g and 82% respectively.
