An HIVOL sampler is an instrument used to measure the mass concentration of solid particles present in atmospheric air. This consists of a fan that sucks air at a volumetric rate Q-103/min through a filter that traps solid particles in the air vapor. The filter is walked before and after sampling, which lasts for a certain time interval and the increase in the mass of the filter is equal to the mass of the particles present in the ambient air that passes through the filter during that time. An HIVOL sample is carried out for n interval Ah-24h, and by measuring the mass Mp of the collected particles it is known to be 1.34 g. Determine the density pp of the particles present in the environment in units of micrograms per cubic meter (g/m3).
