draw an atomic/molecular level representation of what you think the solute (KI) looks like before mixing. Indicate and label the strongest interactions between particles.

NeC 2. Another common unit of concentration is % mass/volume (m/v). Calculate the % mass/volume for the 1.38 M NaCl solution that was prepared in lab. m. mass of NaCl % NaCl (-) x 100% %3D Volume sol'm

4. From the information below, determine the mass of NH3 in 500. grams of concentrated ammonia? DATA FROM BOTTLE % Solute by Mass Density Ammonia, concentrated 28 0.90 g/mL Mass nerc

3. An important conversion factor that you must memorize and use in this course is: 1 mg/L = 8.34 lb/million gallons a) Start with a value of 1 mg/L and use dimensional analysis to prove that this conversion factor is correct: Show that 1 mg/L = 8.34 lb/million gal. b) A wastewater treatment plant adds 5 mg/L of a commercial polymer to raw water to enhance removal of colloidal particles during settling. If the flow rate of water into the facility is 100 MGD, how many pounds of polymer are needed each year? (hint, use the required conversion factor 1 mg/L = 8.34 lb/million gallon to perform the calculation)

A solution is 8.25% by mass ammonium acetate. How many grams of ammonium acetate would be in 235 ml of solution that has a density of 1.18g/ml

You make a solution using a solid solute (5g) in water (total volume 100mL). The molar mass of the solute is 110 g/mol. What is the Molarity?

17.1 g of a nonelectrolyte was dissolved in 33 g of a solvent.  The pure freezing point of the solvent was 2.5 C and the Kf value was 3.21 C/m.  The freezing point after the nonelectrolyte was dissolved was -4.55 C.  What is the molar mass of the nonelectrolyte? Round your answer to the ones position.
