Concentrated sodium hydroxide (NaOH) is 19.4 M, has a density of 1.54 g/mL, and is a strong electrolyte. What is the molality of 19.4 M NaOH? Assume NaOH(aq) dissociates completely to produce two moles of ions per mol NaOH. Calculate the vapor pressure above concentrated NaOH at 35.0 °C, given vapor pressure of H2Ois 42.2 mm Hg at 35.0 °C.
