A core sample has a dry "weight" of 20 g and after completely saturatedwith water has a "weight" of 22.5 g. The density of water is 1.0 gm/cm3. Bulkvolume is 9.9 cm3 .
(a) find the pore volume of the core
(b) Find the porosity of thecore
(c) Find the density of rock matrix in g/cm3
(d) Using the Table given below, determine the type of the rock to which the core may belong.
Rock Type Grain (or rock matrix) density values in g/cm3
Massive Salt 2.14
Sandstone 2.65
Limestone 2.71
Dolomite 2.88
