Answer to Question #208936 in General Chemistry for Nana

Question

500cm cube of a saturated solution of ALCL contains 26.6g dissolved in it at 45°c. What is the solubility in moles dm cube at this temperature

Answer 1

Volume = 500 cm³ which is equal to (500/1000)dm³ = 0.5 dm³

Moles of AlCl₃ = 26.6/133.34 = 0.199 moles = 0.2 moles

Solubility = 0.2/0.5 = 0.4 moles/dm³
