Colligative properties depend on 7) A) the molar mass of the solute. B) the chemical properties of the solute. C) the masses of the individual ions. D) the chemical properties of the solvent. E) the number of particles dissolved

the number of particles dissolved

Explanation:

Colligative properties are properties that depend on the number of solutes dissolved in solution, that is, they depend on the amount (number of moles) of solute present in solution. They include; freezing point depression, boiling point elevation and osmotic pressure.

altitude, density, pressure

air gets less dense the higher the altitude and also the air pressure is less as altitude rises.
