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 :
[tex]\%=\dfrac{\text{calculated value-actual value}}{\text{actual value}}\times 100\\\\=\dfrac{71.8-70.2}{70.2}\times 100\\\\=2.27\%[/tex]
So, the required percentage error is 2.27%.
