A poly-dispersed aerosol consists of spherical particles within the size range 1.0-10.0 micrometers. The particles are of uniform density (2.0g/cm^3), wth the following mass size distribution function: m(dp)=A/dp, with A=50 microgram m^-3, valid over the 1.0-10.0 micrometer size range. Calculate the mass concentration of the aerosol, the number concentration of the aerosol, and the mass mean particle diameter.
