Answer:
Percent error = 5.6%
Explanation:
Given data:
Measured value of density by students = 2.85 g/cm³
Accepted density of aluminium = 2.70 g/cm³
Percent error = ?
Solution:
Formula:
Percent error = [ Measured value - accepted value / accepted value ]× 100
Now we will put the values in formula:
Percent error = [ 2.85 g/cm³ - 2.70 g/cm³ / 2.70 g/cm³ ]× 100
Percent error = [0.15/2.70 g/cm³ ] × 100
Percent error = 0.056× 100
Percent error = 5.6%
