Question

An estimated measurement was guessed of 10.4 mL and the actual measurement was 9.7 mL. What is the percent error?

Answer 1

percent error = 6.73%

Solution

Percentage error expresses as percentage the differences between actual vale and the estimated value.It is mainly used in Chemistry and other Science field

An estimated measurement was guessed of 10.4 ml and the actual measurement was 9.7 ml.

percent error = mode of [ (measured - actual)/actual] x 100

Here Measured = 10.4 ml

Actual = 9.7 ml

percent error =mode of [(10.4 - 9.7)/9.7] x 100 =7.21%

Answer 2

We have been given that an estimated measurement was guessed of 10.4 ml and the actual measurement was 9.7 ml.

Let us find error percent of our given value.

`\text{Error percent}=\frac{\text{Estimated measurement- Actual measurement }}{\text{Actual measurement}} \cdot 100`

`\text{Error percent}=(10.4-9.7)/(9.7) \cdot 100`

`\text{Error percent}=(0.7)/(9.7) \cdot 100`

`\text{Error percent}=0.07216494845 \cdot 100`

`\text{Error percent}=7.216494845\approx 7.22`

Therefore, error percentage of the measurement is 7.22%.
