Question

If 2000 mL/min of air was sampled for 30 min at 18 °C and 103 kPa what is the volume
occu pied in liters at temperature of 25 °C and pressure of 1 atm. If 3.2 ng of toluene
(C.HSCH3) was collected at 25 °C and pressure of 1 atm, what is the ambient
concentration of toluene in ng/L and in ppbv?

Expert Solution

Step 1

$Given : Volume flow rate of air = 2000 \frac{mL}{\min} Time = 30 \min Temperature = 18 ° C = (273 + 18) K = 291 K Pressure = 103 kPa condition Temperature = 25 ° C = (273 + 25) K = 298 K Pressure = 1 atm = 101.3 kPa$
