B. Prelab/Post lab Questions: 1. What is the difference between a weak and a strong electrolyte? How does it affect conductivity? 2. 26.5 g of sodium hydroxide (NaOH) is added to 735 mL of water. Calculate: a) the molality of the solution. b) the mass % of NaOH in the solution. c) the mole fraction of water in the solution. 3. A commonly purchased disinfectant is a 3.0% (by ma ) solution of hydrogen peroxide (H2O2) in water. Assuming the density of the solution is 1.0 g/mL, calculate the molarity and molality of H2O2
