Homework Answers
Buoyant force = volume of body submerged * density of liquid * g
Apparent weight = weight of body in air - buoyant force
Given :
mass of rock = M = 8.98 kg
apparent mass = m = 6.07 kg
d = density of water = 1000 kg/m^3
Let V be the volume of rock, which can be expressed as V = M/D
Lets assume density of rock be D.
Now using the formula :
Apparent weight = weight of body in air - buoyant force
The density of the rock is 
. [answer]
