5.6%

Explanation:

The percent error for the student’s calculated density of Aluminum is 5.56%

The actual value of the density of Aluminium = 2.70 g/cm^3

Measured density of Aluminium = 2.85 g/cm^3

Given that the formula for percentage error is;

Absolute value of (True value - measured value)/True value * 100

Percent error for the student’s calculated density of Aluminum =

Absolute value of (2.70 - 2.85)/2.70 * 100

= 5.56%
