Answer:
The answer is 40.96%
Step-by-step explanation:
The percentage error of a certain measurement can be found by using the formula

From the question
actual density = 2.49g/mL
error = 2.49 - 1.47 = 1.02
We have
![p(\%) = (1.02)/(2.49) * 100 \\ = 40.96385542...](https://img.qammunity.org/2021/formulas/chemistry/college/jpq9talbc5sz0edfg7vo2khcpasq1uv8ji.png)
We have the final answer as
