HCl collection efficiency was 80%. 3 mcg/ mL in control blank impinger. What was the steel pickler’s exposure in ppmv? Determine an 8-hour TWAE of a scrap metal processor to Pb dust and fume with exposures of 3 hours, 15 minutes to 17 mcg Pb/m3; 97 min to 565 mcg Pb/ m3; and 2 hours, 10 minutes to 46 mcg Pb/m3. The worker wore an approved HEPA dust/fume/mist filter cartridge respirator for 5-½ hours. (306) 4. 172 grams of liquid phosgene splash onto a floor. What gas volume quickly results after evaporation at an air temperature of 23°C and an atmospheric pressure of 742 mm Hg?

The value of k is a function of temperature and pressure. 4. 2. How many kilograms of ammonia are in a 3000 ft3 tank when the gauge pressure is 950 lb/in2, and the ammonia temperature is 31°C? Atomic weights of nitrogen and hydrogen are 14 and one, respectively. 0821 L-atm/mole-K) × 304 K 223,579 gram-moles × 17 grams/mole = 3,800,843 grams = 3801 kg ammonia 23. What is the volume if the gas in Problem 22 expanded to atmospheric pressure at a temperature of 20°C as might occur during a rapid tank rupture?

Most measurements for all four types of mixtures showed greater concentrations of benzene in air than were predicted by Raoult’s law. Of five tests with naphtha-based rubber cements, one yielded measured values of benzene concentration in air in agreement with calculated values, the other four showed measured benzene concentrations in air to be 3–10 times greater than those calculated using Raoult’s law. Substantial deviation from Raoult’s law is not always the case, however, even with benzene.
