An electrical contact material produced by infiltrating silver into a porous tungsten carbide (WC) compact. The density of the final composite is 12.7 g/cm3. Assuming that half the pores are filled with silver, calculate a) the volume fraction of silver in composite, b) the volume fraction of pores in the WC compact prior to infiltration, and c) the original density of the WC compact before the infiltration. pure WC has a density of 15.77 g/cm^3
