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
C.. it wants to try to remain in a state of equilibrium or equal
with that being said it wants to electrons to be equal to the number of electrons as much as possible
its like static friction when you rub a balloon on your head... you are replacing electrons for neutrons and that why it can stick to a wall after you rub it on your head because a wall only has negative atoms and when you rub the balloon on your head it takes some positive and charges it up positively and attracts to the negative atoms on the wall
