9. an irregularly-shaped sample of aluminum (al) is put on a balance and found to have a mass of 43.6 g. the student decides to use the water-displacement method to find the volume. the initial volume reading is 25.5 ml and, after the al sample is added, the water level has risen to 41.7 ml. find the density of the al sample in g/cm3. (remember: 1 ml = 1 cm3.)
