The solubility of sulfamethoxypyridazine (SMP) in a 10% by volume mixture of dioxane and 90% by volume of water is 1.8 mg/mL at 25 o C. Calculate a. molarity, b. molality, and c. mole fraction of SMP. The density of the liquid, dioxane, is 1.0313 g/mL, of the solution 1.0086 g/mL, of water 0.9970 g/mL, and of the solvent mixture 1.0082 g/mL. The molecular weight of SMP is 280.32 g/mole, that of dioxane is 88.10, and that of water is 18.015.
