A student measures the mass and volume of a
substance and calculates its density as 1.40 g/mL. The
correct, or accepted, value of the density is 1.30 g/mL.
What is the percentage error of the student's
measurement?

Respuesta :

Answer:

The answer is 7.69 %

Explanation:

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

[tex]P(\%) = \frac{error}{actual \: \: number} \times 100\% \\ [/tex]

From the question

actual number = 1.30 g/mL

error = 1.40 - 1.30 = 0.1

We have

[tex]p(\%) = \frac{0.1}{1.3} \times 100 \\ = 7.692307...[/tex]

We have the final answer as

7.69 %

Hope this helps you
