Artist 52 [7]

Answer:

The answer is

<h2>2.00 %</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 measurement = 46.37 g

error = 47.25 - 46.37 = 0.88

The percentage error of the measurement is

P(\%) =  \frac{0.88}{46.37}  \times 100 \\  = 1.89777873...

We have the final answer as

<h3>2.00 %</h3>

Hope this helps you
