Copper has a density of 8.96 g/cm3. of a cylinder of copper weighing 48.85 g is dropped into a graduated cylinder containing 20.00 ml of water, what will be the new water level

First step is to calculate the volume of the copper cylinder as follows:

density = mass / volume

volume = mass / density = 48.85 / 8.96 = 5.45 mL

Then we add the volume of the cylinder to the volume of water to get the new water level:

New water level = 20 + 5.45 = 25.45 mL
