Question

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).
