To determine the mole fraction from vapor pressure, you can use Raoult's Law. This law states that the vapor pressure of a solution is directly proportional to the mole fraction of the solvent in the solution. By measuring the vapor pressure of the solution and knowing the vapor pressure of the pure solvent, you can calculate the mole fraction of the solvent in the solution using the formula:
Mole fraction of solvent Vapor pressure of solution / Vapor pressure of pure solvent

What is the vapor pressure of a water solution in which the molefraction of HgCl2 is 0.163 at 25C?
To calculate the vapor pressure of the water solution with a mole fraction of HgCl2 of 0.163 at 25°C, you would need to use Raoult's Law. The vapor pressure of the solution would be equal to the mole fraction of water multiplied by the vapor pressure of pure water at that temperature. The vapor pressure of HgCl2 can be ignored since its mole fraction is given.
How do you calculate the vapor pressure of a solution?
To calculate the vapor pressure of a solution, you can use Raoult's Law. This law states that the vapor pressure of a solution is equal to the vapor pressure of the pure solvent multiplied by the mole fraction of the solvent in the solution. This formula can be expressed as P(solution) X(solvent) P(solvent), where P(solution) is the vapor pressure of the solution, X(solvent) is the mole fraction of the solvent, and P(solvent) is the vapor pressure of the pure solvent.
How does a solution containing a chemical with a high vapor pressure be low in volatility?
Well vapor pressure also depends on the mole fraction of a substance. Vapor pressure= Mole fraction* Total pressure of the solution. If the Mole fraction of a volatile substance in the solution is decreased its vapor pressure increases. Thus the volatility of the substance barely plays the role. Of course, if the solution has no volatile substance there cannot be any vapor pressure in the container.

What is the equilibrium vapor pressure at 35 Celsius above a solution of 3.80 moles of volatile C6H12 in 8.20 moles of C5H10O?
The equilibrium vapor pressure is dependent on the mole fraction of the volatile component in the solution. In this case, we need to calculate the mole fraction of C6H12 and then use Raoult's law to determine the equilibrium vapor pressure. The equations are p = X_C6H12 * P0_C6H12 and X_C6H12 = n_C6H12 / (n_C6H12 + n_C5H10O).

A mixture of methane and helium is placed in a 2.0 l flask at 27 degrees the partial pressure of mathane is 0.72 ATM and the partial pressure of helium is 0.22 ATM What is the mole fraction of ch4?
To find the mole fraction of CH4, we first need to calculate the total pressure of the mixture. Total pressure = partial pressure of CH4 + partial pressure of He = 0.72 ATM + 0.22 ATM = 0.94 ATM. Then, we use the formula for mole fraction: Mole fraction of CH4 = (partial pressure of CH4) / (total pressure). Mole fraction of CH4 = 0.72 ATM / 0.94 ATM ≈ 0.766.
How can you calculate the vapour pressure of water over the solution at 90 degrees Celsius vapour pressure of water at 90 degrees Celsius is 525.8mmHg?
You can use Raoult's law to calculate the vapor pressure of water over the solution. The formula is P_solution = X_solvent * P°_solvent, where P_solution is the vapor pressure of the solution, X_solvent is the mole fraction of the solvent (water in this case), and P°_solvent is the vapor pressure of pure water at 90 degrees Celsius (525.8 mmHg). Calculate the mole fraction of water in the solution and then use it in the formula to find the vapor pressure.

What are true the vapor pressure of 1 m ethylene glycol C2H6O2 is the same as the vapor pressure of 1 m kCI where the solvent is water is it true or false?
False. The vapor pressure of a solution is lower than that of the pure solvent in a colligative property called Raoult's law. The vapor pressure of a solution is directly proportional to the mole fraction of the solute present, so the presence of the solute (ethylene glycol or KCl) will lower the vapor pressure compared to pure water.
Calculate the mass of propylene glycol that must be added to 0.340 kg of water to reduce the vapor pressure by 2.88 ATM at 40 degrees Celsius at 40 degrees Celsius equals 55.3torr?
To calculate the mass of propylene glycol needed, we can use Raoult's law. Given that the vapor pressure of pure water at 40 degrees Celsius is 55.3 torr and the desired vapor pressure when mixed is 2.88 atm, we can calculate the mole fraction of propylene glycol needed. From this, we can find the mass of propylene glycol required to achieve this mole fraction when combined with 0.34 kg of water.
