Question

An irregularly shaped stone was lowered into a graduated cylibder holdong a volume of water equal to 2 ml the height of the water rose to 7ml if the mass of the stone was 25g what was its densety

Answer 1

Density = mass / volume.
Volume = Final reading - Initial reading = 7 - 2 = 5 cm^3
Hence,
D = 25 / 5 = 5 g/cm^3
Remember, cubic centimeters is a volume unit (the same volume as 1 milliliter)
Hope that helped!
