4 Determine the mass of your dye contained per milliter of water enhancer concentrate using the following steps a Divide the molar concentration of the stock solution by its vol/vol concentration to determine the moles of your dye per milliliter of water enhancer concentrate. Sample Calculation: Convert the value from step a to units of mg dye/ml water enhancer. The molar masses for each dye are given in Table 7.12. Record your results in Table 7.13. b Sample Calculation: TABLE 7.12 Molar Masses of Various Dyes Dye Red No. 40 Yellow No. 5 Blue No. 1 Molar Mass i/mol) 450.44 465.39 746.87
