10 mL saturated potassium oxalate , potassium oxalate Mw = 184.23 g mol-1, solubility of potassium oxalate in water at 25°C = 360. calculate the concentration a saturated solution of potassium oxalate
Homework Answers
solubility of potassium oxalate in water at 25°C = 360 mg / ml = 0.360 g / ml
0.360 g K2C2O4 . H2O = mass / molar mass = 0.360 g / 184.23 = 1.954 * 10^-3 mole.
thus
mole of K2C2O4 in one ml = 1.954 * 10^-3 mole.
1 ml = 0.001 L
thus
concentration a saturated solution of potassium oxalate = 1.954 * 10^-3 mole / 0.001 L = 1.954 mole / L
therefore,
concentration a saturated solution of potassium oxalate = 1.954 mole / L
