A medical company separates methanol (CH₃OH)) and ethanol (CH₃CH₂OH) by distillation. In one run, the starting solution was 25% methanol and 75% ethanol by mass at 25°C. In the liquid, the mole ratio of methanol to ethanol was ________, and in the vapor it was ________. The vapor pressures for methanol and ethanol at this temperature are 92 torr and 45 torr, respectively. A) 0.48; 2.0 B) 2.0; 0.48 C) 0.33; 2.0 D) 0.48; 0.33 E) 2.3; 0.55

Question

Quizplus · Accepted Answer

The mole ratio of methanol to ethanol in the liquid is calculated using their masses and molar masses, resulting in approximately 0.48. The vapor ratio is determined using Raoult's Law and Dalton's Law, resulting in approximately 2.0.
