(a) Palladium (Pd) is an element with properties similar to those of platinum. It is useful in eliminating harmful emission produce by internal combustion engines. Two students were given identical cylindrical “palladium” bars with the following data: Mass = 96.03 g; Length = 10.7 cm; Diameter = 9.82 mm; Density = 12.02 gcm-3 Show the calculations that Student K and S would do if: Student K was asked to determine whether his bar was made of pure palladium. Student S was asked to calculate the grams of ethyl alcohol (d = 0.789 gcm-3) his bar would displace.
