Q
Q: What is Raoult's Law primarily used to determine?
Solution: Raoult's Law states that the vapor pressure of a solvent in a solution is directly proportional to the mole fraction of the solvent.
Steps: 7
Step 1: Understand that Raoult's Law is a principle in chemistry.
Step 2: Know that it deals with solutions, which are mixtures of two or more substances.
Step 3: Identify the main components: a solvent (the liquid part) and a solute (the substance dissolved in the solvent).
Step 4: Learn that Raoult's Law helps us find out how much vapor pressure the solvent will have when mixed with the solute.
Step 5: Remember that vapor pressure is the pressure of the vapor above a liquid in a closed container.
Step 6: Realize that the law states the vapor pressure of the solvent in the solution is related to how much of the solvent is present compared to the total amount of all substances in the solution (this is called the mole fraction).
Step 7: Conclude that Raoult's Law is primarily used to determine the vapor pressure of a solvent in a solution.
