Air samples show the following contaminant concentrations in an 8-hour shift (from 8: 00 a. m. to 4: 00 p. m.): 1. trifluorobromomethane, 0.1% from 11: 00 a. m. to 2: 00 p. m. 2. propane, 0.05% all day 3. phosgene, 1 part per million at 2: 00 p. m., with a duration of 15 minutes (a) assuming that no other contaminants are present, does the full-shift atmosphere meet osha standards? (b) to exactly meet osha standards, how much more or less time for the phosgene exposure would be permissible provided other contaminants remain as previously stated?

Solomon chemical company makes three products, b7, k6, and x9, which are joint products from the same materials. in a standard batch of 320,000 pounds of raw materials, the company generates 70,000 pounds of b7, 150,000 pounds of k6, and 100,000 pounds of x9. a standard batch costs $3,840,000 to produce. the sales prices per pound are $10, $14, and $20 for b7, k6, and x9, respectively. (a) allocate the joint product cost among the three final products using weight as the allocation base. (b) allocate the joint product cost among the three final products using market value as the allocation base. (c) allocate the joint product cost among the three final products using weight as the allocation base.
