Question

What is the Percent yield is 4.65 got copper is produced by 1.87 percent yield is got copper is produced when 1.87 grams of aluminum reacts with excess copper (11) sulfate

Answer 1

The percent yield is 70.486%

Step-by-step explanation:

`3CuSO_(4)+2Al\longrightarrow Al_(2)(SO_(4))_(3)+3Cu\\\\Weight\:of\:Al=1.87g\\54g\:of\:Al\:will\:give\:190.5g\:of\:Cu\\`

`1.87g\:of\:Al\:gives=(190.5*1.87)/(54)=6.597g\:of\:Cu\\ \\Weight\:of\:Cu\:obtained=4.65g\\Theoretical\:Yield=6.597g\\Experimental\:Yield=4.65g\\Percent\:Yield=(Experimental\:Yield)/(Theoretical\:Yield)*100=(4.65)/(6.597)*100=70.486\%`

Hence, the percent yield is 70.486%
