Answer:
Percent error = - 8.1 %
Explanation:
Given data:
Actual mass = 27.20 g
Theoretical mass = 25.01 g
Percent error = ?
Solution:
Formula:
Percent error = theoretical value- actual value/ actual value × 100
Now we will put the values in formula.
Percent error = 25.01 - 27.2 / 27.2 × 100
Percent error = -2.19 / 27.2 × 100
Percent error = -0.081 × 100
Percent error = - 8.1 %
Answer: Divide the mass of the object by its volume to yield the density of the object. For example, the object density = mass / (Vf – Vi). Compare the measured density to that of pure gold (19.3 g/cc) to determine whether the object is made of pure gold.
