Question

Can somebody help me. Will mark brainliest.

Answer 1

Answer:

2.27%

Explanation:

The observed value of the boiling point = 71.8°C

The actual value of the boiling point = 70.2°C

We need to find the percentage error of the student's measurement. The percentage error in any value is given by :

$\%=\dfrac{\text{calculated value-actual value}}{\text{actual value}}\times 100\\\\=\dfrac{71.8-70.2}{70.2}\times 100\\\\=2.27\%$

So, the required percentage error is 2.27%.
