If a marker was dropped into a graduated cylinder filled with 20 mL of water, and the water level rose to 26 mL, what would the be volume of that marker?

density

=

2.9

g/cm

Explanation:

We're asked to find the density of the rock, given some mass and volume information.

We're given that the mass of the system before the rock was added was

120

g

. The mass after the rock was added was

250

g

, so the rock's mass is

m

The initial volume of water in the graduated cylinder was

30

mL

, and the volume after the rock was added read

75

mL

, so the rock's volume is

V

The equation for the density of the rock is

And so we have
