Question

question 10. a student calculates the density of iron as 6.80 g/cm³ by using lab data for mass and volume. a handbook reveals that the correct value is 7.86 g/cm³. what is the percentage error?

Explanation:

Step1: Calculate absolute error

$|6.80 - 7.86| = 1.06$

Step2: Compute percentage error

$\frac{1.06}{7.86} \times 100 \approx 13.5\%$

Answer:

13.5%
