If a mold assessor runs an air sampling pump at a flow rate of 28 liters per minute for 3 minutes, what total volume of samples is collected?

84 liters
90 liters
70 liters
40 liters

The correct answer is: 84 liters

To determine the total volume of air sampled, you multiply the flow rate of the air sampling pump by the amount of time it runs. In this case, the flow rate is 28 liters per minute, and the pump is running for 3 minutes. Calculating the total volume involves using the formula: Total Volume = Flow Rate × Time Substituting in the given values: Total Volume = 28 liters/minute × 3 minutes = 84 liters. This calculation clearly shows that the total volume of air collected during the sampling period is 84 liters, confirming that this is the correct answer.
