The concentration of suspended particulates in the atmosphere
can be measured by forcing air through a semi-porous paper that
filters the particulates from the air. Determine the suspended
particulate concentration (in milligrams, mg) from the
measurements presented as following: airflow rate = 0.71 cubic
meters per minute air sample time = 24 hours weight of filter
paper before sampling = 4.5722grams weight of filter paper after
sampling = 4.7424 grams.
