Normal saline is made by putting 9g of NaCl into 1L of water. What is the normal boiling point and normal freezing point of this solution?
I want to know how to get a molality from this condition except considering a molality same as a molarity.

Table salt has a Ksp in water of 37.9 M2 at 25°C. What will be the maximum boiling temperature of an aqueous sodium chloride solution made by saturating a solution(establishing a dynamic equilibrium of the salt and ions in solution)at 25°C, filtering off any solid remaining, then bringing the solution to a boil. a)Find the molality (include units) for sodium chloride in a saturated aqueous solution: b)Find the boiling point elevation and boiling point of the saturated solution. (If you...

Colligative properties, such as boiling point elevation, depend on the number of dissolved particles in solution. For nonelectrolytes, no dissociation occurs, and so you can use the number of moles of solute to calculate both molality and molarity. In contrast, electrolytes dissociate, and therefore the molality and molarity must be calculated based on the number of moles of dissociated particles or ions. There are two ions per formula unit of NaCl. Therefore, we would expect the freezing-point depression ΔTf of...
