Percent Error is the difference between the true value and the estimate divided by the true value and the result is multiplied by 100 to make it a percentage. The percent error obviously can be positive or negative; however, some prefer taking the absolute value of the difference.

The formula is the absolute value of the experimental value (minus) the theoretical value divided by theoretical value times 100.

% error = (|Your Result - Accepted Value| / Accepted Value) x 100

What is the percent of error in evaluating the molecular mass of a compound if the experimental value was 105.2 amu and the known value was 107.5 amu?

The percent error is calculated using the formula: |(experimental value - known value) / known value| x 100. Plugging in the values: |(105.2 - 107.5) / 107.5| x 100 ≈ |-2.3 / 107.5| x 100 ≈ 0.021 x 100 = 2.1% Therefore, the percent error in evaluating the molecular mass of the compound is approximately 2.1%.


What is the percent error for a measured value of 3.24 and a correct value of 3.02?

Percent error is calculated using the formula: ((measured value - correct value) / correct value) x 100. Plugging in the values, we get ((3.24 - 3.02) / 3.02) x 100 = (0.22 / 3.02) x 100 ≈ 7.28%.


The accepted value for the boiling water is 100.0 degrees Celsius when you measure this value in the laboratory your result is 98.5 degrees Celsius What is the percent error?

The percent error is calculated by taking the absolute difference between the accepted value and the measured value, dividing by the accepted value, and multiplying by 100%. In this case, the absolute difference is 100.0 - 98.5 = 1.5. Dividing by 100.0 and multiplying by 100% gives a percent error of 1.5%.


A student determined that the density of a sample of tin is 8 00 mL when the actual density of tin is 7 28 mL What was the percent error in the student's calculation?

The student's calculation resulted in a density that is higher than the actual density. To calculate the percent error, the formula (|measured value - actual value| / actual value) x 100 is used. Plugging in the values, the percent error would be [(8.00 - 7.28) / 7.28] x 100 = 9.89%.


What does it mean if the percent yield is over 100?

Percent error formula?

Divide the calculated or estimated error by the magnitude of the measurement. Take the absolute value of the result, that is, if it is negative, convert to positive. This would make the percent error = | error / measurement |.

What is the measured the density of Copper to be 68.7 gcm3 The accepted density of Copper is 63.5 gcm3 What was your percent error?

To calculate percent error, we can use the formula: Percent Error = [(Measured Value - Accepted Value) / Accepted Value] x 100. Plugging in the values: Percent Error = [(68.7 - 63.5) / 63.5] x 100 = (5.2 / 63.5) x 100 = 0.082 x 100 = 8.2%.
