33. 0.2347 g of an ionic compound MX (135.32 g/mol) completely dissociates into its corresponding ions M* and X¯ when dissolved to 0.90 L solution. What is the Ksp of the ionic compound? 3.7 x 10 5.0 x 107 6.8 x 10 None of these 34. A 0.1504-g sample of impure Na₂CO3 (106.00g/mol) was analyzed via Volhard method. After adding 50.0 mL of 0.07106 M AgNO3, the sample was back-titrated with 0.06485 M KSCN requiring 11.69 mL to reach the end point. What is the purity of the Na₂CO3 sample? 98.5% 95.7% 89.0% None of these
