Answer:
0.24 g/mL
Explanation:
The density of an object is given by the ratio between its mass and its volume:

where
m is the mass of the object
V is its density
In this problem, we have:
m = 7.0 g is the mass of the object
The volume of an irregular shaped object can be measured by putting it into water, and by measuring the difference in water volume.
In this case,
is the initial volume of water
is the final volume of water
So the volume of the object is

Therefore, the density of the object is:
