Answer to Question #126485 in General Chemistry for Hannah Ruth

Question

An irregularly shaped metal object has a mass of 28.73 g. It is lowered into a 100-mL graduated cylinder that contains 35.2 cm^3 water. The water level rises to 44.8 cm^3. What is the density of the metal?

Answer 1

The volume of water displaced by the object equals 44.8 - 35.2 = 9.6 cm³.

D = 28.73 g / 9.6 cm³ = 2.99 g/cm³

Answer: 2.99 g/cm³
