3. (a) The data obtained from a liquid pycnometry test are as follows: pyenometer mass =32.383g; pycnometer+powder =41.923g; pycnometer+ water =84.229g; pycnometer + powder + water =91.170g. Calculate the apparent density of the powder. The apparent density of water and air at 24C are Dwater=1g/cm3 and Dair=0.00119g/cm3. Answer: 3.667g/cm3. (b) If the ultimate density of the powder is 3.98g/cm3, what is the closed pore volume in the particles? Answer: 0.205cm3
