Question

question 8. a handbook gives the density of calcium as 1.54 g/cm³. based on lab measurements, what is the percentage error of a density calculation of 1.25 g/cm³?

Explanation:

Step1: Find absolute error

$|1.25 - 1.54| = 0.29$

Step2: Calculate percentage error

$\frac{0.29}{1.54} \times 100\% \approx 18.83\%$

Answer:

18.83%
