After installation of water dams, it could lead to many societal issues. One could be the distortion of the natural environment caused by flooding. It could also lead to some geological damage such as earthquakes and could depress the earth's surface.
One form of Raoult's Law states that the vapor pressure of a solution of a non-volatile solute at certain temperature is equal to the vapor pressure of the pure solvent at the same temperature multiplied by the mole fraction of the solvent, this is:
p = X solvent * P pure solvent,
X solvent = number of moles of solvent / total number of moles.
Here the solute is 13.6 g of C12 H10 and the solvent is 26.4 g C6H6.
=>
moles of solvent = mass in grams / molar mass
molar mass of C6H6 = 6 * 12 g/mol + 6 * 1g/mol = 78 g/mol
moles of solvent = 26.4 g / 78 g/mol = 0.33846 mol
molar mass of C12H10 = 12 * 12g/mol + 10*1g/mol = 154 g/mol
moles of solute = 13.6 g / 154 g/mol = 0.08831 mol
=> X solvent = 0.33846 / (0.33846 + 0.08831) = 0.793
=> p = 0.793 * 100.84 torr = 79.97 torr ≈ 80.0 torr
Answer: 80.0 torr
