3.3 g of a sample of quinine was dissolved and made up to 100 cm³. 25 cm³ of this solution was made up to 250 cm³. A fluorescence reading of 200 was obtained. A 100 cm³ sample of 50 ppm quinine was prepared. When it was run under the same conditions as the sample, a fluorescence intensity of 135 was found. Calculate the % wt/wt quinine in the original sample.
