(a) Carbon monoxide (CO) is a poisonous gas because it binds very strongly to the oxygen carrier hemoglobin in blood. A concentration of by volume of carbon monoxide is considered lethal to humans. Calculate the volume in liters occupied by carbon monoxide in a room that measures long, wide, and m high at this concentration.
(b) Prolonged exposure to mercury (Hg) vapor can cause neurological disorders and respiratory problems. For safe air quality control, the concentration of mercury vapor must be under . Convert this number to g/L.
(c) The general test for type Il diabetes is that the blood sugar (glucose) level should be below per deciliter (mg/dL). Convert this number to micrograms per milliliter .
Prolonged exposure to mercury even at relatively low but toxic concentrations in the air is known to cause permanent mental disorders, insomnia, and pain and numbness in the hands and the feet, among other things. Therefore, the maximum allowable concentration of mercury vapor in the air at workplaces is regulated by federal agencies. These regulations require that the average level of mercury concentration in the air does not exceed . Consider a mercury spill that occurs in an airtight storage room at in San Francisco during an earthquake. Calculate the highest level of mercury concentration in the air that can occur in the storage room, in and determine if it is within the safe level. The vapor pressure of mercury at is 0.173 Pa. Propose some guidelines to safeguard against the formation of toxic concentrations of mercury vapor in air in storage rooms and laboratories.
It is required to calculate the highest level of mercury concentration in the air that can occur during a mercury spill, and to determine if that value is within safe level. It is also required to propose some guidelines to safeguard against the formation of toxic concentrations of mercury vapours in storage rooms and laboratories.
