If the specific heat of copper is experimentally determined to be 0.410 L/gC, what is the percent error from the known value of 0.385 j/gC?

To determine the percent error, the formula used is:

[

\text{Percent Error} = \left( \frac{\text{Experimental Value} - \text{True Value}}{\text{True Value}} \right) \times 100%

]

In this case, the experimental value is the determined specific heat of copper, which is 0.410 J/g°C, and the known or true value is 0.385 J/g°C.

Substituting in these values gives:

[

\text{Percent Error} = \left( \frac{0.410 - 0.385}{0.385} \right) \times 100%

]

Calculating the numerator:

[

0.410 - 0.385 = 0.025

]

Now, plugging the value into the equation:

[

\text{Percent Error} = \left( \frac{0.025}{0.385} \right) \times 100% \approx 6.49%

]

The calculation shows that the percent error between the experimental and known specific heat of copper is approximately 6.49%. This computation reflects how much the experimental value deviates from
