Calculate the freezing point of a 0.05500 m aqueous solution of NaNO3. The molal freezing- point-depression constant of water is 1.86°C/m. (assume 100% ionization of NaNO3) my (incorrect ) answer was -.205...what did i do wrong? I assumed the m is molality not molarity. it seemed like a straight forward plug and chug. T = i * kf * m i = 2  kf = 1.86 C/m m = .05500

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
