Question

A graduated cylinder contains 17.5 mL of water. A metal cube is placed in the cylinder and the water level rose to 20.3 mL. The metal cube has a mass of 30 g. What is the density of the metal cube

Answer 1

10.71 g/mL

Step-by-step explanation:

Initial Volume = 17.5 mL

Final Volume = 20.3 mL

Volume of cube = Final Volume - Initial Volume = 20.3 mL - 17.5 mL = 2.8mL

Mass of cube = 30g

Density = Mass / Volume

Density = 30 / 2.8 = 10.71 g/mL
