In lab, you calculate the density of an iron rod to be 7.30 g/cm3. The accepted value
OLga [1]

Answer:

<h2>6.41 %</h2>

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 density = 7.80 g/cm³

error = 7.30 - 7.80 = 0.5

We have

p(\%) =  \frac{0.5}{7.8}  \times 100 \\  = 6.410256...

We have the final answer as

<h3>6.41 %</h3>

Hope this helps you
