### Problem StatementA student dissolves 20.0 g of benzoic acid (C\(_7\)H\(_6\)O\(_2\)) in 125. mL of a solvent with a density of 1.07 g/mL. The student notices that the volume of the solvent does not change when the benzoic acid dissolves in it.**Task:** Calculate the molarity and molality of the student's solution. Ensure each of your answer entries has the correct number of significant digits.![Graphical representation to input molarity and molality with units](The image shows placeholders to enter the calculated molarity and molality values, with the molarity indicated in units of molarity and molality in units of molality.)### Details1. **Given Data:** - **Mass of benzoic acid:** 20.0 g - **Volume of solvent:** 125. mL - **Density of solvent:** 1.07 g/mL2. **Molar Mass Calculation:** - **Molar mass of benzoic acid (C\(_7\)H\(_6\)O\(_2\)):** - Carbon (C): 12.01 g/mol - Hydrogen (H): 1.01 g/mol - Oxygen (O): 16.00 g/mol Formula: C\(_7\)H\(_6\)O\(_2\) - Molar mass = (7 × 12.01) + (6 × 1.01) + (2 × 16.00) - Molar mass = 84.07 + 6.06 + 32.00 = 122.13 g/mol3. **Molarity Calculation:** - **Volume of solution in liters:** 125 mL = 0.125 L - **Moles of benzoic acid:** - Moles = Mass / Molar mass = 20.0 g / 122.13 g/mol = 0.164 mol - **Molarity (M):** - Molarity = Moles / Volume = 0.164 mol / 0.125 L = 1.31 M4. **Molality Calculation:** - **Mass of solvent in grams:**

Which of the following statements is WRONG? Select the correct response: A solution must be in a liquid form; that is, it can neither be in gaseous nor solid form. A saturated solution exhibits equilibrium between the dissolved and the undissolved solute. The solubility of most solid compounds increases with increasing temperature. An unsaturated, or say, homogeneous solution, is the solution that is frequently seen in our daily life can dissolve more soluble solute if added.

Colligative properties are those that depend on the number of solute particles. Because electrolytes dissociate into ions, the concentration of particles in the solution is greater than the formula-unit concentration of the solution. For example, if 1 mol of NazSO4 totally dissociates, 3 mol of ions are produced (2 mol of Nat ions and 1 mol of SO, ions). Thus, a colligative property such as osmotic pressure will be three times greater for a 1 M NazSO, solution than for a 1 M nonelectrolyte solution. Part A Assuming complete dissociation of the solute, how many grams of KNO3 must be added to 275 mL of water to produce a solution that freezes at - 14.5 °C? The freezing point for pure water is 0.0 °C and Kf is equal to 1.86 °C/m. Express your answer to three significant figures and include the appropriate units. • View Available Hint(s) However, complete dissociation of electrolytes does not always occur.
