A mixture of ideal miscible liquids E and F is distilled at 760mm-Hg pressure. At the start of the distillation, the mole per cent of E in the mixture is 90.0, while that of F is 10.0. The vapor is condensed and found to contain 15.0 mole per cent of E and 85.0 mole per cent of F. calculate: (a) the partial vapor pressure (P) of E and F in this mixture; (b) the vapor pressure (P') of pure E and F. -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.111.76.37
