Question

You are trying to determine the identity of an unknown metal object using density. You measure the volume by displacement using a graduated cylinder. The initial volume is 14.7 mL, and the final volume is 23.5 mL. The mass is measured using a balance and is determined to be 68.895 g. The calculation you use to find the answer is: $$

Answer 1

The formula you use is Density = (mass) / (volume) .

The calculation for this particular object is

Density = (68.895 g) / (23.5 mL - 14.7 mL)

Density = (68.895 g) / (8.8 mL)

Density = 7.8 g/mL
