A geologist finds that a Moon rock whose mass is 9.28 kg has an apparent mass of 6.23 kg when submerged in water. What is the density of the rock?
here,
mass of moon rock , m = 9.28 kg
apparent mass , m' = 6.23 kg
let the density of rock be p
buoyant force = g * ( m - m')
density of water * Volume of mass * g = g * (m - m')
pw * ( m /p) = ( m - m')
1000 * ( 9.28 /p) = ( 9.28 - 6.23)
solving for p
p = 3042.6 Kg/m^3
the density of the rock is 3042.6 kg/m^3

To verify her suspicion that a rock specimen is hollow, a geologist weighs the specimen in air and in water. She finds that the specimen weighs twice as much in air as it does in water. The density of the solid part of the specimen is 2.49 × 103 kg/m3. What fraction of the specimen’s apparent volume is solid?
