(a) carbon monoxide (co) is a poisonous gas because it binds very strongly to the oxygen carrier hemoglobin in blood. a concentration of 8.00 x 10^2 ppm by volume of carbon monoxide is considered lethal to humans. calculate the volume in liters occupied by carbon monoxide in a room that measures 17.6 m long, 8.80 m wide, and 2.64 m high at this concentration. (b) prolonged exposure to mercury (kg) vapor can cause neurological disorders and respiratory problems. for safe air quality control, the concentration of mercury vapor must be under 0.050 mg/m^3. convert this number to g/l. (c) the general test for type il diabetes is that the blood sugar (glucose) level should be below 120 mg per deciliter (mg/dl). convert this number to micrograms per milliliter (î¼g/ml).
