47. Solution to Chemistry Problem
29.2 To determine copper in the alloy, 250.0 cm3 of a colored solution was obtained from a 0.3200 g sample after dissolution and treatment with ammonia; its optical density in a cell with a layer thickness of 10 mm was 0.275. Determine the mass fraction of copper in the alloy (in %); the molar absorption coefficient of copper ammine is 400.
