A vitamin C 142g/mol tablet weighing 0.562g is crushed as well as dissolved in enough water to form 500mL of solution. Ten milliliters of this solution is after that diluted to 250mL. The absorbance of the solution is 0.241 in a 1cm cell. Explain what is the percentage of vitamin C in the tablet. The molar absorptivity is 7415.
