$3.06\times {10}^{-3}$ g of the amino acid glycine, ${\text{C}}_{\text{2}}{\text{H}}_{\text{5}}{\text{NO}}_{\text{2}}$

25 lb of the herbicide Treflan, ${\text{C}}_{\text{13}}{\text{H}}_{\text{16}}{\text{N}}_{\text{2}}{\text{O}}_{\text{4}}\text{F}$ (1 lb = 454 g)

0.125 kg of the insecticide Paris Green, ${\text{Cu}}_{\text{4}}\left({\text{AsO}}_{\text{3}}\right)\text{2}{\left({\text{CH}}_{\text{3}}{\text{CO}}_{\text{2}}\right)}_{\text{2}}$

325 mg of aspirin, ${\text{C}}_{\text{6}}{\text{H}}_{\text{4}}\left({\text{CO}}_{\text{2}}\text{H}\right)\left({\text{CO}}_{\text{2}}{\text{CH}}_{\text{3}}\right)$
