Density is a measure of how much mass is contained in a given volume.

• Density is calculated by dividing the mass of an object by its volume.

• It is commonly expressed in units such as grams per cubic centimeter (g/cm^3) or kilograms per liter (kg/L).

• Objects with higher density have more mass packed into a smaller volume, while objects with lower density have less mass in a larger volume.

• For example, lead has a higher density than feathers because a given volume of lead is much h...read more

Roult's law states that the vapor pressure of a solution is directly proportional to the mole fraction of solvent present.

• Vapor pressure of a solution is lower than that of the pure solvent.

• The decrease in vapor pressure is directly proportional to the amount of solute added.

• Roult's law is applicable for ideal solutions.

• Mathematically, P = P°solvent * x(solvent), where P is the vapor pressure of the solution, P°solvent is the vapor pressure of the pure solvent, and x(solvent)...read more
