1. If a 15.0 mL solution of 2.5 M NaCl is diluted to a volume of 100 mL. (1.00 x 10' ml.). what is the molarity (M) of the diluted solution? Show all your steps with the formula. 2. A solution of 0.40 M NISO, has an absorbance, X. If this solution is diluted to give a 0.1 M solution, answer the following: Will the absorbance of the 0.10 M solution decrease or increase? a. b. By what factor will the absorbance increase or decrease? 3. Predict the intensity of the light bulb (bright, dim, or no light) for the following solutions and classify them as weak electrolytes, strong electrolytes, or nonelectrolytes. Aqueous Solutions of Compounds Intensity of Light Type of Electrolyte C,H,OH (1) + H,0 C,H,OH (aq) KOH (s)+ H,O K* (aq) + OH (aq) NH,(g) + H,0-NH,"(aq) + OH (aq)
