Assuming no heat loss to the Styrofoam and surroundings, what is the expected heat capacity of a calorimeter consisting of 5.00 mL (5.00 g) of water? The specific heat capacity of water is 4.184 J/(g*°C)

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.
