You are asked to determine the identity of an unknown liquid and can measure only one phisical property. you heat the liquid and record that the liquid turns to vapor at 100 c. this demonstrates which physical property? a) melting point b) boiling point c)ability to conduct electricity d) malleability

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.
