Question

In lab, you calculate the density of an iron rod to be 7.30 g/cm3. The accepted value

for the density of iron is 7.80 g/cm3. What is your percent error?

Answer 1

6.41 %

Step-by-step explanation:

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

`P(\%) = (error)/(actual \: \: number) * 100\% \\`

From the question

actual density = 7.80 g/cm³

error = 7.30 - 7.80 = 0.5

We have

`p(\%) = (0.5)/(7.8) * 100 \\ = 6.410256...`

We have the final answer as

6.41 %

Hope this helps you
