Answer:
0.24%
Explanation:
The following data were obtained from the question:
Measured value = 42.1 g
Actual value = 42 g
Percentage error =?
Percentage error can be obtained by using the following formula:
Percentage error = |Measured value – Actual value | / Actual value × 100
With the above formula, we can obtain the percentage error as follow:
Measured value = 42.1 g
Actual value = 42 g
Percentage error =?
Percentage error = |42.1 – 42| / 42 × 100
Percentage error = 0.1/42 × 100
Percentage error = 10/42
Percentage error = 0.24%
Therefore, the percentage error is 0.24%
