by always contain acids. E) conduct heat. 2. What is the vapor pressure above a solution prepared by dissolving 0.500mol of a nonvolatile solute in 3.19mol of hexane at 49.6C ? P hexsen =400.0 torr at 49.6C. (25 pts) Psc=XsuPsy(319+0.5)319=(3.199)(400torr)(10.500)(40tirr)=1076twe 3. If the molality of ions in an aqueous solution of MgF2 is 0.930m and the salt dissociates completely, what is the molality of MgF2 ? (20 pts) 1L0.930mMgF2=0.930MMgF2 4. If a general chemistry student adds 200.0g of sugar to a cup of water (250mL) at room-temperature, what type of solution is obtained? Show your work. (at room temperature: solubility of sugar =91.0g per 100g of water; density of water =1g/mL)(15pts) A) Unsaturated B) Saturated C) Soluted (D) Supersaturated E) Oversaturated W. Wich process defines how molecular compounds form ions upon dissolution? ( 10 pts) A) ionization B) composition C) division D) dissolution E) decomposition 6. What is the freezing point of a solution made from 2.60 mol of octane (C8H18) dissolved in 2 kg of benzene? (For benzene, freezing point =5.50C;K1=5.12C/m)(20pts) Tf(0.38)kf=kfm=kf(1.30M)2kg2.66N=1.30=36C +5 las: PSL=XSvPSV,XA=ntotalnA,Tf=Kfm,=MRT,Cg=kPgStep by Step Solution
