![\%\ yield =56.14](https://img.qammunity.org/2020/formulas/chemistry/college/mepv9t9jobdvwhhl088og7kte5d0xfzpa4.png)
Step-by-step explanation:
The expression for the calculation of the percentage yield for a chemical reaction is shown below as:-
![\%\ yield =\frac {Experimental\ yield}{Theoretical\ yield}* 100](https://img.qammunity.org/2020/formulas/chemistry/college/229vcpubtdoyogq15pbwu5owd6anft282p.png)
Given , Values from the question:-
Theoretical yield = 47.2 g
Experimental yield = 26.5 g
Applying the values in the above expression as:-
![\%\ yield =(26.5)/(47.2)* 100](https://img.qammunity.org/2020/formulas/chemistry/college/lwt6o79169roa9mp964mtmn03hscfsvgyh.png)
