1) In a laboratory experiment, a student found that a 136-mL aqueous solution containing 2.889 g of a compound had an osmotic pressure of 36.4 mm Hg at 298 K. The compound was also found to be nonvolatile and a nonelectrolyte. What is the molar mass of this compound?

________g/mol

2) The nonvolatile, nonelectrolyte DDT, C₁₄H₉Cl₅ (354.5 g/mol), is soluble in benzene C₆H₆.

Calculate the osmotic pressure (in atm) generated when 14.5 grams of DDT are dissolved in 279 mL of a benzene solution at 298 K.

_________atm

3) The ionic compound AgNO₃ is soluble in water. Calculate the osmotic pressure (in atm) generated when 8.68 grams of silver nitrate are dissolved in 92.6 mL of an aqueous solution at 298 K. The van't Hoff factor for AgNO₃ in this solution is 1.62.

_________atm
