Describe how to calculate mass fraction and weight percent Describe how to calculate parts per million (ppm). Contrast Molality and Molarity Define what is meant by Colligative Properties? Boiling point elevation (provide the equation and explain it) Freezing point lowering (provide the equation and explain it) Osmotic Pressure (define & provide the equation) Please show your work for each of these problems Convert 2.5 ppm to weight percent. Please show your work. Calculate the mass in grams of solute required to prepare each of these solutions. A) 250 ml of .25 M KCl b. 150 ml of .350 M Na_2SO_2 Calculate the molarity of the solute in a solution containing 6.18 grams of MgNH_2PO_2 in 250ml of solution. Calculate the molality of a solution made by dissolving 6.8 grams of NaCl in 250 ml of water. Calculate the freezing and boiling points (at 760mm Hg) of a solution of 4.00 grams of urea CO(NH_2)_2 dissolved in 75 grams of water.Explanation / Answer
The dissolving process involves three major intermolecular attraction forces which tell whether a solute is soluble in solvent or not if yes than how much. There are three attractive forces between solute solute, solvent solvent or solute solvent molecules. In order to dissolve solute and solvent the forces must overcome the solute solute and solvent. solvent force . If it is less than that than they are immisible.
