Percent yield is 108.3%
Explanation:
Percent yield is the ratio of experimental yield and the theoretical yield multiplied by 100.The expression for the percent yield is given as,
Percent yield = [tex]$\frac{actual yield}{theoretical yield}\times100[/tex]
It is given that the experimental or actual yield is 3.9 g and the theoretical yield calculated using stoichiometry is 3.6 g, then the percent yield is calculated as,
Percent yield = [tex]$\frac{3.9}{3.6}\times100 = 108.3[/tex]
So the percent yield is 108.3%.
