A solution is made using 13.9 percent by mass C*H_{2}*C*l_{2} in CHCl 3 At 30 C, the vapor pressure of pure C*H_{2}*C*l_{2} is 490 mm Hg, and the vapor pressure of pure CHCl 3 is 260 mm Hg. The normal boiling point of CHCl 3 is 61.7 C. If the molality of C*H_{2}*C*l_{2} is 1.90 m , what is the boiling point in C of the solution ? ( Kb for CHCl 3 is 3.67^ C/m)
