QUESTION 12 The concentration of carbon monoxide (CO) in cigarette smoke reaches 400 ppm. For this...
Based on the “National Ambient Air Quality Objectives”, the acceptable hourly average concentration of carbon monoxide (CO) is 35 mg/m3 . Find the acceptable concentration of CO in ppm if the temperature is -30oC and pressure is 0.92 atm. Express the concentration as a percent by volume.
The concentration of carbon monoxide in a trench is found to be 0.037 g/m3 a. What is this concentration in mg/m3 ? b. How does this concentration compare to the TLV of 25 ppm, assuming an ambient temperature of 77°F (25°C) and pressure of 760 torr (760 mm Hg). c. What would the concentration (ppm) be at an ambient temperature of 32°F (0°C) and pressure of 760 torr (760 mm Hg).
The average concentration of Carbon Monoxide in a city's air in 2006 was 4.5 ppm. The average atmospheric pressure of the city is 754 Torr. (a) Calculate the partial pressure of CO. (b) Calculate the number of CO molecules in 1.0L of this air at a temperature of 25°C
Exhaust gas emitted by a particular automobile contains 20 g of carbon monoxide (CO) for every km driven. If this car is driven 30 km, how much carbon monoxide will have been emitted, and what would be the volume of the carbon monoxide after it cools to 25°C at a pressure of 1 atm? Assume carbon monoxide (and the atmosphere) acts as an ideal gas. Per km of travel, what volume of air could be polluted by the carbon monoxide...
Caleulate the 0.45 ppm NO, concentration at 25°C and 1 atm pressure as mg/m' and ug/m 5. Estimate the stoichiometric air to fuel ratio for a 100% ethanol (CHCH2OH) fuel One mole of CH,CHOH-46g: one mole of O;-32g; one mole of N, 28g Assume the following reaction. 6 CH CH,OH+36 O; +135.36 N;12 CO + 18 H,O+135.35 N (Ans:18) Solid waste with the density of 110 kg/m is spread in a 0.5m layer at a landfill. If a steel wheel...
Many studies have been conducted to determine the concentration of CO (carbon monoxide) near freeways with various conditions of traffic flow. The basic technique involves measuring CO concentrattions with a spectrophotometer. These machines are quite delicate and have to be calibrated every day. If the machine reads close to 70 ppm on the span gas, it’s ready for use; if not, it has to be adjusted. Each data set below represents some readings on span gas. Assume the Gaussian model,...

A balloon is filled with He gas to a volume of 2.10 L at 35 °C. The baloon is...
1. Calculate the primary NAAQS concentration limit for 502 in units of ug/m' at standard temperature and pressure (STP:T - 25*C, P = 1 atm). 2. Fuel X9-6000 is 95.8% efficient in an airplane engine. The unburned fuel leaves as VOCS in the exhaust. For each kg of fuel X9-6000 (Molecular Weight, MW-98), the engine exhausts 20 kg of gases (MW = 28 g/mol). What is the fraction of VOCs in the exhaust (ppm)? ncinerator burns 30 tonnes of plastic...
