Raoult's law for a volatile component of a solution states $P_i$ equals:
A$P_i^0 - x_i$
B$x_i + P_i^0$
C$x_i / P_i^0$
D$x_i \cdot P_i^0$
Answer & Solution
Correct answer: D. $x_i \cdot P_i^0$
Raoult's law: the partial vapour pressure of a volatile component is its vapour pressure when pure ($P_i^0$) multiplied by its mole fraction in solution ($x_i$). The total pressure is the sum over all volatile components (Dalton's law).
