Question

In an exercise to teach students how to use an analytical balance, the instructor gives a student a one dirham coin which has been pre-weighed ( accepted value)as 4.6026 g. The weight that the student obtains for the same one dirham coin is 4.6013 g. What is the percentage error in the students' reading

Answer 1

0.028%

Step-by-step explanation:

From the question given above, the following data were obtained:

Accepted value = 4.6026 g

Measured value = 4.6013 g.

Percentage error =..?

Thus, we can obtain the percentage error in the student's reading as follow:

Percentage error = |measured value – accepted value|/accepted value × 100

Percentage error = |4.6013 – 4.6026| / 4.6026 × 100

Percentage error = 0.0013 / 4.6026 × 100

Percentage error = 0.13/4.6026

Percentage error = 0.028%

Therefore, the percentage error in the student's reading is 0.028%
