A student carries out an experiment to determine the density of an irregularly shaped metal object.
Initially, a measuring cylinder containing some liquid is placed on a digital balance. The balance reads 150 g.
The student then carefully lowers the metal object into the liquid until it is completely submerged. The balance now reads 285 g, and the liquid level rises.
Which two measurements must the student make to determine the density of the metal object?
The increase in mass and the increase in the volume reading of the liquid.
The final mass reading and the increase in the depth of the liquid.
The increase in mass and the increase in the depth of the liquid.
The final mass reading and the increase in the volume reading of the liquid.
