The theoretical value for the density of steel is 7.79 g/cm3. If Teresa measured the density of a steel ball to be 8.05 g/cm3, what was her experimental error?

3.34%

Step-by-step explanation:

We want to figure out the percent error. This is calculated by the formula:

(measured value - actual value) ÷ (actual value)

In this case, the measured value is 8.05 g/cm³, while the actual value (also known as the theoretical value) is 7.79 g/cm³. So plug these in:

(measured value - actual value) ÷ (actual value)

(8.05 - 7.79) ÷ (7.79) = 0.26 / 7.79 ≈ 0.0334 = 3.34%

The experimental error was 3.34%.

Step-by-step explanation:

Step 1:  Find the difference between the numbers

Teresa's Value - Theoretical Value

       8.05          -          7.79

0.26 is the difference

Step 2:  Find the experimental error

 The experimental error was approximately 3.34%
