Questions: Homework 4 Question 1 of 23 (1 point) I Question Attempt: 1 of 3 Six different aqueous solutions are represented in the beakers below, and their total noted. The solvent molecules are omitted for clarity. Part 1 of 5 Which solution has the highest molarity? Select the single best answer. Solution B Solution A Solution F Solution E Part 2 of 5 Which solutions have the same molarity? Check all that apply. Solutions C, D, and E Solutions A and F Solutions A and E Solutions A, B, and E None of the above

Solution Steps

Molarity is defined as the number of moles of solute divided by the volume of the solution in liters. Since the number of solute molecules is shown and the volumes are given, we can determine the highest molarity by looking for the highest number of solute molecules within the smallest volume.

Solution A: 8 molecules/ 50 mL Solution B: 10 molecules/ 50 mL Solution C: 6 molecules/ 50 mL Solution D: 4 molecules/ 50 mL Solution E: 3 molecules/ 25 mL Solution F: 4 molecules/ 25 mL

Solution B has the highest number of solute molecules (10) in a 50 mL volume, meaning it has the highest molarity.

Solutions C, D, and E have the same molarity. We can determine this by comparing the ratio of solute molecules to volume: Solution C: 6 molecules/50 mL = 0.12 molecules/mL Solution D: 4 molecules/50 mL = 0.08 molecules/mL Solution E: 3 molecules/25 mL = 0.12 molecules/mL

Final Answer:
