3) Over a period of 1 year, 1 gallon of each of the four common chemicals shown below has been spilled in an unventilated 20ft20ft8ft room at 68F and 1atm pressure in separate incidents. With the above Information and the data shown below: a. Calculate how many mL of each chemical would have to evaporate in order to reach the TLV concentration and how much would have to evaporate to reach the IDLH level. b. Determine how long it would take each chemical to reach the TLV concentration and how long it would take to reach the IDLH level? c. Calculate what air flow rate in ft2/min would be needed to ventilate the room to keep the chemical concentrations below their respective TLVs. d. Comment on the hazards of the bromine spill. e. Comment on the need for ventilation or controls in working with the other three chemicals. 1ft3=0.0283 meter cube Gas constant PV = n R T R=(atmL)/( gmole K)
