1. Calculate the pressure needed to prevent osmosis when 10.0 g KCl is added to 150 mL of water at 25oC.
20.1 atm 40.1 atm 65.7 atm 80.2 atm 160 atm

2. Van't Hoff's factor, i is incoporated into some equations due to
a constant value that adjust for the pressure in the lab some electrolytes break up into ions a correction factor that makes data match up with hypothesis Van't Hoff factor I is a constant that corrects all osmotic equations none of the above

3. What is the boiling point of a 4 m solution of BaCl2 in water? (Boiling point elevation constant for water is 0.5oC/m)
102oC 104oC 106oC 94oC 6oC

4. Coagulation is destoyed by:
heating shaking adding an electrolyte A&B A&C

5. How many grams of NaOH are contained in 250 mL of 0.500 M NaOH?
0.125 g 5 g 10 g 0.25 g 0.5 g
