1. A solution is made by dissolving 25.8 g urea (CH4N2O) a nonelectrolyte, in 275 g water. Calculate the vapor pressure at 25oC (Vapor pressure of water at 25oC is 23.8 torr)
97 torr 23.2 torr 23.8 torr 0.97 torr 24 torr

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. 64 g of a nonvolatile nonelectrolye is dissolved in 2705 g H2O.
11 g 22 g 44 g 66 g 5 g

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
