Question

A student takes an object with an accepted mass of 120.0 grams and masses it on their
own balance. They record the mass of the object at 113.7g. What is their percent
error?

Answer 1

Answer:

The answer is 5.25 %

Explanation:

The percentage error of a certain measurement can be found by using the formula

$P(\%) = \frac{error}{actual \: \: number} \times 100\%$

From the question

actual mass = 120 g

error = 120 - 113.7 = 6.3

The percentage error is

$P (\%) = \frac{6.3}{120} \times 100 \\ = 5.25$

We have the final answer as

5.25 %

Hope this helps you
