student decides to use the waterdisplacement 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.) mass = 43.6 g final volume = 41.7 mL initial volume = 25.5 mL density = ? g/cm3 Volume of Al = Final Volume Initial Volume
= 41.7 mL 25.5 mL = 16.2 mL D = M = 43.6 g = 2.69 g/mL = 2.69 g/cm3 V 16.2 mL Find the volume that 35.2 g of carbon tetrachloride (CCl4) will occupy if it has a density of 1.60 g/mL. mass = 35.2 g density = 1.6 g/cm3 volume = ? mL
