You are given an 18% solution of sodium imidazole. What mass of imidazole (in g) would be in 20 mL of this solution? a. You need to use the sodium imidazole stock solution from Q11 to make a dilute imidazole solution (final volume 180 mL) at a final concentration of 0.2 M. The molecular weight of imidazole is 90 g/mole. What volume of imidazole stock would you use (mL)? b. You need to use the sodium imidazole stock solution from Q11 to make a dilute imidazole solution (final volume 180 mL) at a final concentration of 0.2 M. The molecular weight of imidazole is 90 g/mole. What volume of water would you add (mL)?
