1. Determine the experimental van't Hoff factor for 0.0230M sodium iodide that has an osmotic pressure of a 0.367atm at 25C. Dr. Callahan, SJF's amazing biochemist, has purified an unknown protein. To determine the identity of the unknown protein, he dissolved 25.00mg of the unknown protein in 50.0mL buffer. The osmotic pressure of solution was found to be 0.716mmHg at 5.00C. What is the molar mass of the gene fragment? 3. Determine the van't Hoff factor for each of the following. Justify vour choice by stating if the chemical is an ionic salt, strong acid, strong base, weak acid, weak base, or non-electrolyte. Show a representative drawing for the molecule or compound in water. Water molecules should not be shown. a. CH3CH2CH2CO2CH2CH(CH3)22 b. CH3CH2CH2OH c. LiOH d. K2SO3
