    1g soil has been spiked with 0.1ml of 100 ppm (v/v) trimethylbenzene and subsequently extracted with 250 mL pentane. The extract is then measured with GC-FID. Calculate the recovery when the extract gives a peak area for trimethylbenzene of 750, while 20 ppm solution of trimethylbenzene gives a peak area of 50000.
