Answer:
Explanation:
Since we are not given the mole fraction of ethanol and water; we will solve this theoretically.
Using Raoult's Law:
For water:
where 
of water = 12.5 mmHg
Then, the vapor pressure of water:
For ethanol:
and the of ethanol = 32.1 mmHg
Then, the vapor pressure of ethanol:
The total vapor pressure 
The total vapor pressure = 
Answer:
The right answer is "60.56 atm".
Explanation:
As we know,
Vander wall's equation is:
⇒ 
or,
⇒ 
Here,
a = 3.59 L² atm mol⁻²
b = 0.0427 L mol⁻¹
By putting the values in the above equation, we get
⇒ 
31.79 g Cu / 63.5 g/mol Cu ---> 0.5
0.5 * (2/1) ---> 1
1 * 107.9 g/mol Ag
107.9 grams
