Arock is placed on a balance and its mass is determined as 18.3 g. when the rock is then placed in a graduated cylinder that originally contains 11.1 ml of water, the new volume is roughly 17.0 ml. how should the density of the rock be reported?

Answer : The density of rock reported should be, 3.1 g/mL

Explanation :

Mass of rock = 18.3 g

Original volume of water = 11.1 mL

New volume of water = 17.0 mL

First we have to calculate the volume of rock.

Volume of rock = New volume of water - Original volume of water

Volume of rock = 17.0 mL - 11.1 mL

Volume of rock = 5.9 mL

Now we have to determine the density of rock.

Formula used :

Thus, the density of rock reported should be, 3.1 g/mL

answer: point c: b. 1/2 potential, 1/2 kinetic, point a: 3/4 of its potential energy, point d or b: 3/4 potential, 1/4 kinetic
