Suppose that the mixture in problem 4 is at 15 OC, where the pure vapor pressures are 12.5 mmHg for water and 32.1 mmHg for etha
EleoNora [17]

Answer:

Explanation:

Since we are not given the mole fraction of ethanol and water; we will solve this theoretically.

Using Raoult's Law:

P_A = (P_o)_A*X_A

For water:

(P)w = P_o \times \text{mole fraction of water}

where P_o of water = 12.5 mmHg

Then, the vapor pressure of water:

(P)w = 12.5 \ mmHg \times \text{mole fraction of water}

For ethanol:

P_E = P_o \times \text {mole fraction of ethanol}

and the P_o of ethanol = 32.1 mmHg

Then, the vapor pressure of ethanol:

P_E = 32.1 \ mmHg \times \text {mole fraction of ethanol}

The total vapor pressure T_P = P_W + P_E

The total vapor pressure = (12.5 \ mmHg \times \text{mole fraction of water}) + (32.1 \ mmHg \times \text {mole fraction of ethanol})
