CCC Scale, Proportion, and Quantity Estimate how long it would take you to count a dozen eggs. Now estimate how long it would take you to count
the number of atoms in a single egg. If you knew how many atoms were in a
single egg, how would you use that information to estimate the number of
atoms in a dozen eggs?

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.
