Calculating Percent Yield of Silicon Carbide (SiC)

How to calculate the percent yield of Silicon Carbide?

If 64.4 kg of silicon carbide is recovered from the reaction of 125 kg of sand and 74.0 kg of carbon, what is the percent yield of silicon carbide?

Calculating Percent Yield

The percent yield of Silicon Carbide (SiC) can be calculated by finding the theoretical yield based on the balanced chemical reaction, then calculating the percent yield using the formula: (actual yield / theoretical yield) x 100%. The actual yield is given as 64.4 kg.

Explanation

The percent yield of Silicon Carbide (SiC) produced can be calculated by first determining the theoretical yield based on the balanced chemical equation. As you have the mass of both reactants, the theoretical yield needs to be calculated for both and the smallest value used as the theoretical yield, as the other reactant would be in excess. After determining the theoretical yield, the percent yield can be calculated using: (actual yield / theoretical yield) x 100%.

In this case, the actual yield of Silicon Carbide is given as 64.4 kg, but you will need the balanced chemical reaction equation to continue.
