Se han muestreado vapores de alcohol isopropílico usando un tubo de carbón activado durante 8 horas a un flujo de 20 ml/min: ¿cuál fue el volumen del aire muestreado?

For this case we can translate the given statement as:

Isopropyl alcohol vapors have been sampled using an activated carbon tube for 8 hours at a flow of 20 ml/min: what was the volume of the sampled air?

By definition, the volumetric flow rate is given by:

Where:

V: It's the volume

t: It's time

Then, the volume is given by:

According to the problem data we have:

Substituting the values we have:

Finally, the volume of the sample is:

9600ml

9600ml
