A molocule i think sorry if im wrong
Answer:
2.44 %
Explanation:
Given that,
The calculated value of specific heat of water to be 4.29 J/g°C
The actual value of the specific heat of water is 4.18J/g°C
We need to find the percentage error of the student
![\text{Percentage error}=\dfrac{|\text{actual value-calculated value}|}{\text{actual value}}\times 100\\\\\%=\dfrac{4.18-4.29}{4.49}\times 100\\\\\%=2.44](https://tex.z-dn.net/?f=%5Ctext%7BPercentage%20error%7D%3D%5Cdfrac%7B%7C%5Ctext%7Bactual%20value-calculated%20value%7D%7C%7D%7B%5Ctext%7Bactual%20value%7D%7D%5Ctimes%20100%5C%5C%5C%5C%5C%25%3D%5Cdfrac%7B4.18-4.29%7D%7B4.49%7D%5Ctimes%20100%5C%5C%5C%5C%5C%25%3D2.44)
Hence, the student's percent error is 2.44 %.
