As a quality control check, a sample of acetone is taken from a process to determine the concentration of suspended particulate matter. An 850-mL sample was placed in a beaker and evaporated. The remaining suspended solids were determined to have a mass of 0. 001 g. The specific gravity of acetone is 0. 79 g/cm3. (a) Determine the concentration of the sample as mg/L. (b) Determine the concentration of the sample as ppm.
