The main weapon on a military tank is a cannon that fires a blunt projectile specially designed to cause a shock wave when it hits another tank. The projectile fits into a finned casing that improves its accuracy. Calculate the mass of the projectile, assuming it is a cylinder of uranium (density = 19.05 g/cm3) that is 105 mm in diameter and 30 cm in height. The volume of a cylinder is given by the equation V = r2h

Below are some potentially useful conversion factors. 1 lb 1 gallon 1 quart = = = 453.6 g 4 quartts 0.946 L -33 The precipitation of aluminum hydroxide, Al(OH)3 (Ksp = 1.3 × 10−³³), is commonly used to purify potable water. It forms a spongy precipitate that settles slowly, carrying even very small suspended particles down with it, thereby removing all finely divided matter and most microbes. Part A The Ksp can be used to find the minimum concentration of hydroxide ions required to start the precipitation of Al(OH)3 given a concentration of aluminum ions, and thus determine the pH above which this precipitation occurs. Calculate this pH value if 4.40 lb of aluminum sulfate, Al2(SO4)3, is added to 2150 gallons of water (with a negligible change in volume). Express your answer numerically to two decimal places after the dot.
