Problem P 8.5, SGI (2016). A public toilet problem. Do parts (a), (b), and (c) as listed here, not as listed in book (part c is different in the book). Calculate the concentration of the 1,4-dichlorobenzene (DCB) in grams per cubic meter of air assuming that (a) you get the vapor pressure data for DCB from the CRC Handbook of Chemistry and Physics (data provided with the problem). Answer: 13 g m-3 (b) you have no time to look for vapor pressure data, but you know the boiling point (Tb = 174.0C) and the melting point (Tm = 53.1C) of DCB. Compare this result with the result using the vapor pressure data in part (a). Answer: 4.6 g m-3 (c) What would be the DCB concentration in the air of a public toilet located in Death Valley (60C)? Which approach, data or estimate, did you use, and why? Answer: 106 g m-3
