10.0 g of soil containing N-nitrosodimethylamine (NDMA) was extracted by two portions of acetone (25 mL each). Extracts were combined to the final volume 42+2 mL and evaporated to the final volume 1.00+0.02 ml. Analysis of the evaporated extract by GC-MS showed NDMA concentration 27+1 ng/mL. Calculate NDMA concentration in soil sample and its uncertainty.
