How do you find the molality for the two problems and which statement is correct? Please help :)
P4. (Sec. 11.1) A solution was prepared by dissolving 10 grams of acetic acid (HC2H3O2) in 265 mL of water. If the density of the solution was measured at 1.031 g/mL, what is the molality of this acetic acid solution? [Hint: Calculate Molarity First] a) Molality=0.633 mol/kg b) Molality = 0.286 mol/kg c) Molality = 0.714 mol/kg d) Molality=0.965 mol/kg e) Molality=0.127 mol/kg P5. (Sec. 11.1) A solution was prepared by dissolving 9.5 grams of sodium hydroxide (NaOH) in 875 mL of water. If the density of the solution was measured at 1.105 g/mL, what is the molality of this NaOH solution? [Hint: Calculate Molarity First]
