The formula to calculate the Vapor Pressure of a Solution is:
\[ \text{VP(solution)} = \text{MF} \times \text{VP(solvent)} \]
Where:
This equation is also known as Raoult’s Law. It describes the change in vapor pressure of a solution based on mole fractions and pressures of the solvent.
Vapor pressure is the pressure exerted by a vapor when it is in thermodynamic equilibrium with its condensed phases (solid or liquid) at a given temperature in a closed system. It is a measure of the tendency of particles to escape from the liquid or solid phase into the gas phase.
Let's assume the following values:
Using the formula to calculate the Vapor Pressure of the Solution:
\[ \text{VP(solution)} = 0.2 \times 0.5 = 0.1 \text{ atm} \]
The Vapor Pressure of the Solution is 0.1 atm.
