Calculating Boiling Point of a Solution: A Joke Problem for Extra Credit

In summary, the professor has posted a take-home problem for extra credit in which students must calculate the boiling point of a 1:1:1 solution of benzene, pentane, and ethylene in a pressurized tank filled with neon at 6 atm pressure. The answer must be accurate to 14 significant figures and students are only allowed to use pen, paper, and a ham. The conversation has turned into a joke and the thread has been closed.

The professor posted a take-home problem for us to solve for extra credit.

Extra credit problem:
Using nothing but pen, paper and a ham, calculate the boiling point of 1:1:1 solution of benzene, pentane, and ethylene in a pressurized tank filled with neon at 6 atm pressure. The Answer must be accurate to 14 significant figures. Hint: account for all the degrees of freedom within the system.How far I've gotten to solving the problem:

(boiling point of benzene + boiling point of pentane + boiling point of ethylene) / 3 = boiling point of the solution accurate to one significant figure.

It's a joke problem. I'm joking.

Doesn't that exclude using PF 🤔?

FAQ: Calculating Boiling Point of a Solution: A Joke Problem for Extra Credit

1. What is the definition of boiling point of a solution?

The boiling point of a solution is the temperature at which the vapor pressure of the liquid in the solution is equal to the external pressure.

2. How is the boiling point of a solution different from that of a pure solvent?

The boiling point of a solution is typically higher than that of a pure solvent. This is because the presence of solute particles in the solution disrupts the intermolecular forces between the solvent molecules, making it more difficult for them to escape into the vapor phase.

3. What factors affect the boiling point of a solution?

The boiling point of a solution is affected by the concentration of solute particles, the nature of the solute and solvent, and the external pressure. Generally, the more concentrated the solution, the higher the boiling point will be. Also, solutions with non-volatile solutes (such as salts) will have a higher boiling point than those with volatile solutes (such as alcohols).

4. How is the boiling point of a solution measured?

The boiling point of a solution can be measured using a thermometer and a boiling point apparatus. The solution is heated until it reaches a constant temperature, which is the boiling point. This temperature can then be compared to the boiling point of the pure solvent to determine the effect of the solute on the boiling point.

5. Why is the boiling point of a solution important?

The boiling point of a solution is important because it can affect the properties and behavior of the solution. For example, in cooking, the boiling point of a solution can determine the cooking time and the texture of the food being cooked. In industrial processes, the boiling point of a solution can impact the efficiency and effectiveness of the process.
