Raoult's law for a volatile component of a solution states $P_i$ equals:

  1. $P_i^0 - x_i$
  2. $x_i + P_i^0$
  3. $x_i / P_i^0$
  4. $x_i \cdot P_i^0$
Show answer and 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).
