Question

There is 35 mg of sodium in a can of Coke. You determine it to be 28 mg. What is your percent error?

Answer 1

Answer:

The answer is

20 %

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 volume = 35 mg

error = 35 - 28 = 7

The percentage error is

$P(\%) = \frac{7}{35} \times 100 \\ = \frac{1}{5} \times 100 \\ = 20$

We have the final answer as

20 %

Hope this helps you

Answer 2

Answer:

20%

Explanation:

The formula is [ |va-ve/ve| * 100% ] where e = error and n = number.

|28-35/35| * 100

|-7/35| * 100%

|-1/5| * 100%

0.2 * 100%

20%

Best of Luck!
