The freezing-point depression constant for mercuric chloride, HgCl2, is 34.3K/m. A 0.849g sample of mercurous chloride, HgCl (empirical formula) dissolved in 50.0g of HgCl2 causes a freezing-point depression of 1.24K. What is the molecular formula for mercurous chloride? [Note: Mercuric chloride, HgCl2, the solvent in this case, is a mercury(II) compound, while mercurous chloride, HgCl, the solute, is a mercury(I) compound.]

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.
