1. What is the concentration of cyclopropane (in units of grams per liter) dissolved in water at , when the C3H6 gas over the solution has a partial pressure of 166 mm Hg? for C3H6 at is 1.2010-2 mol/Latm.
2. The freezing point of benzene, C6H6, is 5.500 C at 1 atmosphere. Kf(benzene) = 5.12 C/m In a laboratory experiment, students synthesized a new compound and found that when 11.48 grams of the compound were dissolved in 218.9 grams of benzene, the solution began to freeze at 4.743 C. The compound was also found to be nonvolatile and a non-electrolyte. What is the molecular weight they determined for this compound?
