Naphthalene is the most abundant single component of coal tar. The composition of coal tar varies with coal type and processing, but typical coal tar is about 10% naphthalene by weight. In industrial practice, distillation of coal tar yields an oil containing about 50% naphthalene, along with twelve other aromatic compounds.

1 Answer Sorted by: 1 If you want 10 ppm copper in 2 liters of water, the best way to make it would be to start with some soluble copper salt, like CuSOX4⋅5HX2O C u S O X 4 ⋅ 5 H X 2 O, make up a convenient concentration (like 1%), then dilute it to 10 ppm. As was mentioned in the comments, copper metal is not noticeably soluble in water.
