4.05 kg + 567.95 g + 100.1 g add the correct value using the correct sig figs and or least precise degree of precision. when i did least degree of precision i got 4718.1g, do we need to convert the kg unit to grams before getting the least degree of precision? since i used 100.1 as dop and if i had converted first the dop of 4.05 or now 4050g the dop is now only to the tens place compared to being in the tenths place

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.
