Calculations for safe temperature:
Record the average specific heats and densities in table 5. Find the thermal conductivity information
given in the background and record it in Table 5.
Perform the following calculations. (You need the subparts under 2 before calculating the Tsafe-)

Expert Solution
Step 1
Given that,
The actual or real density value is d0 = 2.4 g/mL.
And, the calculated density value is dc = 2.12 g/mL.
We have to find out the percent of error in the density calculation.
Formula: The required formula of the percent of error is = .
