CVolume
DSolute mole fraction × Henry's constant: p = K_H × x
Answer & Solution
Correct answer: D. Solute mole fraction × Henry's constant: p = K_H × x
**Henry's law:** p_gas = K_H × x_gas-in-solution.
Used in carbonated drinks (CO₂ solubility), respiration (O₂ in blood).
K_H depends on gas, solvent, T.
