A metal, M, of atomic mass 96 amu reacts with fluorine (19 amu) to form a salt that can be represented as MFx. To determine x, you decide to dissolve 9.18 g of the unknown MFx solid in 100.0 g of water and measure the freezing point depression. You found that the freezing point for this solution was -4.46°C. Assuming the salt completely dissolves and dissociates in solution and the freezing point of water 0.00°C, determine the formula of the salt (i.e. what is the value of x).

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.
