Final answer:
To determine the time required for final clearance air sampling to achieve the minimum volume required, we need to use the formula: Time = Volume / flow rate. Since the minimum volume required is not given, we cannot determine the exact time.
Step-by-step explanation:
In order to determine the minimum volume required by Title 15, Chapter 1 for PCM and TEM analysis, we need to calculate the total volume of air that needs to be sampled. The volume flow rate is given as 9 liters per minute (lpm). To find the minimum time required to achieve the minimum volume, we can use the formula: Volume = flow rate * time. Rearranging the formula to solve for time, we have: Time = Volume / flow rate. Considering the minimum volume required is not given, we cannot determine the exact time required. Hence, we cannot choose any of the given options (a) 10 minutes, (b) 30 minutes, (c) 60 minutes, or (d) 90 minutes without knowing the minimum volume required.
