Matter that has a definite volume but no definite shape is a a. liquid. c. gas. b. solid. d. plasma. 2. if you move a substance from one container to another and its volume changes, the substance is a a. solid. c. gas. b. liquid. d. solution.

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.
