A precipitation process for producing perfect spheres of silica has been developed. The individual particles are so small that most cannot be discerned by the naked eye. Using optical microscopy, the particle size distribution has been measured, with results given in the table below. Using these data on a spreadsheet program:

Determine:

(1) surface-mean diameter

(2) arithmetic-mean diameter

(3) mass-mean diameter

(4) volume-meandiameter
