Question

6- Use Table 11.2 "Solubilities of Some lonic Compounds" to decide if a solution containing 0.000092 g of AgCl per 100 g of H20 is unsaturated, saturated, or supersaturated. 12- Which solvent is NaOH more likely soluble in-CH30H or C6H6? Exercises 11.2 4-What is the molarity of a solution made by dissolving 332g of C6H1206 in 4.66 L of solution? 6-How many moles of NH4Br are present in 88.9 mL of a 0.228 M solution?

Answer 1

12) NaOH is more soluble in CH3OH

4) Moles of C6H12O6 = mass/molar mass = 332/180 = 1.84 moles

Molarity of solution = moles/volume in liters = 1.84/4.66 = 0.395 mol/liter ....Answer

6) Moles of NH4Br = molarity * volume in liters = 0.228 * (88.9/1000) = 0.0203 ....Answer
