Question

What is the concentration in (a) ppm_{v} and (b) percent
by volume, of carbon monoxide (CO) with a concentration of 103
micrograms/m^{3}? Assume a temperature of 25 degrees
celcius and total pressure of 1 atm.

Answer #1

Based on the "national ambient air quality objectives", the
acceptable hourly average concentration of carbon monoxide (CO) is
35mg/m^3. Find the acceptable concentration of CO in ppm if the
temperature is -30'C and pressure is 0.92 atm. Express the
concentration as a percent by volume.

A tank with a volume of 8.6 ft3 contains 5.36 lbmol of carbon
monoxide (CO) gas at a pressure of 3500 lbf/in.2 Determine the
temperature, in °R. Determine the percent error in temperature of
assuming ideal gas behavior at this state for CO.
Please provide the complete answer.

Carbon monoxide and oxygen are in equilibrium at 1
atm, expressed as: co + 0,5 02 → CO2. The partial pressure for
oxygen is 0,004 atm and for carbon monoxide is 0.008 atm. The
chemical equilibrium constant is assumed to be 0,122.
Determine
a. Partial pressure of CO2
b. Ppm of CO2
