According to his prelaboratory theoretical yield calculations, a student's experiment should have produced 1.41 g of magnesium oxide. When he weighed his product after reaction, only 1.33 g of magnesium oxide was present. What is the student's percent yield?
To calculate the percent yield, you can use the formula:
Percent Yield = (Actual Yield / Theoretical Yield) x 100
In this case, the actual yield is 1.33 g of magnesium oxide, and the theoretical yield is 1.41 g. We can substitute these values into the formula to find the percent yield:
Percent Yield = (1.33 g / 1.41 g) x 100
Calculating this expression:
Percent Yield ≈ (0.943 x 100) ≈ 94.3%
Therefore, the student's percent yield is approximately 94.3%.
To calculate the student's percent yield, we need to compare the actual yield (1.33 g) to the theoretical yield (1.41 g) and express it as a percentage.
The formula for percent yield is:
Percent Yield = (Actual Yield / Theoretical Yield) × 100
In this case, the actual yield is 1.33 g and the theoretical yield is 1.41 g. Plugging the values into the formula, we get:
Percent Yield = (1.33 g / 1.41 g) × 100
Dividing 1.33 g by 1.41 g gives us approximately 0.94397. Multiplying by 100 gives us 94.397.
Therefore, the student's percent yield is approximately 94.40%.
