The answer is C 83.9%.

Answer: The correct option is C.

Explanation: For a given chemical reaction:

[tex]R+XY\rightarrow RX+Y[/tex]

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:

[tex]\%\text{ yield}=\frac{\text{Actual yield}}{\text{Theoretical yield}}\times 100[/tex]

Putting the values in above equation, we get:

[tex]\%\text{ yield}=\frac{47.0g}{56.0g}\times 100[/tex]

Percent yield = 83.9%
