Homemade ice-cream is frozen by churning it in a bucket suspended in an ice-water-salt mixture. A typical mix calls for 1.80 kg of salt (NaCl) and 8.75 kg of ice. Compute the mole fraction of NaCl in this mixture after all the ice melts. I already know the mole fraction is 0.0596. I need the second question answered. Thanks! Compute the freezing point of this mixture (in °C).

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.
