Answer: The correct option is C.
Explanation: For a given chemical reaction:
\(R+XY\rightarrow RX+Y\)
The mass of product, RX formed in the reaction = 47.0 g
Theoretical yield of the product, RX = 56.0 g
To calculate percent yield, we use the formula:
\(\%\text{ yield}=\frac{\text{Actual yield}}{\text{Theoretical yield}}\times 100\)
Putting the values in above equation, we get:
\(\%\text{ yield}=\frac{47.0g}{56.0g}\times 100\)
Percent yield = 83.9%
