2. In your own words, explain the main ideas of Dalton's atomic theory. 3. According to Dalton's theory, is it possible to convert atoms of one element into atoms of another? Explain.
4. The law of conservation of mass was introduced in Unit 2 Use Dalton's atomic theory to explain this law.

The content of manganese (mn) in steel was determined spectrophotometrically and with the use of the standard addition method. an unknown sample of mn from a digested steel sample gave an absorbance of 0.185 when analyzed spectrophotometrically. when 5.00 ml of solution containing 95.5 ppm mn was added to 50.0 ml of the unknown steel solution (digested sample), the absorbance was 0.248. calculate the concentration, in parts-per-million (ppm), of mn in the digested steel sample solution.
