Determine the number o moles of ions/atoms/particle in the following: 2.50 miles of k2s (let me know how to do)

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.

Estimate the molar mass of the gas that effuses at 1.6 times the effusion rate of carbon dioxide.
