At 25C the vapor pressure of pure water is 23.76 mmHg and that of seawater is 22.98 mmHg. Assuming that seawater contains only NaCl, estimate its concentration. (HINT: Sodium chloride is a strong electrolyte.) The answer to this question is 0.93 mol/L. Please show the steps that leads to this answer.
