Question

A student calculated the density of copper to be

8.37 g/cm3. The accepted value for the density of
copper is 8.92 g/cm3. What is the percent error in the
density?

Answer 1

The percent error in the density of copper is -6.16%.

Step-by-step explanation:

To calculate the percent error in the density of copper, we can use the formula:

Percent error = (Experimental value - Accepted value) / Accepted value * 100%

Plugging in the values, we get: Percent error = (8.37 g/cm³ - 8.92 g/cm³) / 8.92 g/cm³ * 100%

Simplifying the equation: Percent error = -0.55 g/cm³ / 8.92 g/cm³ * 100%

Calculating the final answer: Percent error = -6.16%

Answer 2

0.55/8.92×100

55/8.92

=6.17%
