    Answer: Porosity= 14% Average density of sandstone is 2.4 gm/cm3 Volume of sandstone core plug= dry weight/density = 57.1/2.4 = 23.79 cm3 Volume occupied by water = (weight of sandstone core plug saturated with water - dry weight of sandstone core)/density of water = (60.6 - 57.1)/1 = 3.5 cm3 Volume of water is same as the volume of pores Porosity= (Volume of pores/Total volume)×100= (3.5/23.79)×100= 14.71%
