Zinc tetraoxosulphate (vi) solution was electrolysed in such a way that 0.5 ampere flowed for 32minutes 10seconds depositing 0.325g of zinc at the cathode. calculate the number of moles of zinc deposited​

Using data from seismic waves, geologists have learned that earth’s interior is made up of several

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.
