Approximately 15% of the particles in a shipment of silver-bearing ore are judged to be argentite (d=7.3 g/cm^3, 87% Ag); the remainder are siliceous (d=2.6 g/cm^3) and contain essentially no silver. a. Calculate the number of particles that should be taken for the gross sample if the relative standard deviation due to sampling is to be 2% or less. b. Estimate the mass of the gross sample, assuming that the particles are spherical and have an average diameter of 3.5 mm.
