From Mr. Vilardi's data, the Red Wing emblem has a density of 1.22g/ml while the bronze ball had a density of 99g/ml. Because the emblem had much less mass, it must have also had
O more volume.
O less volume
O more mass.
less mass.

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.
