In a reaction, 4.82 mol of product has formed but there are no more visible signs of change. Calculations show that as much as 6.05 mol of product could have formed from the chemical amounts of reactants used. The percentage yield is ____________ %

To calculate the percentage yield, we will use the formula:

Percentage Yield = (Actual Yield / Theoretical Yield) * 100

Given that 4.82 mol of product has formed, the actual yield is 4.82 mol.
Calculations show that 6.05 mol of product could have formed, so the theoretical yield is 6.05 mol.

Plugging these values into the formula:

Percentage Yield = (4.82 / 6.05) * 100

Calculating this expression:

Percentage Yield ≈ 79.84%

Therefore, the percentage yield is approximately 79.84%.
