### Volumetric flask and diluted to mark with distilled water

Assignment Help Physics
##### Reference no: EM13546003

A 30.0 mL aliquot of a manganese solution (12.5 mg/mL of manganese, FW=59.94) was added to a 100. mL volumetric flask and diluted to the mark with distilled water. At a wavelength of 525 nm, this solution had an absorbance of 0.625 in a 1.000 cm cuvet. Calculate the molarity of the diluted manganese standard solution. [Express your answer as a decimal number. Do not use scientific notation. Include the leading zero and units.] If you could help i'd greatly appreciate it, this problem was giving me problems for a while
