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.

Question

**Exercise: Calculating Molarity**

**Problem Statement:**

Determine the molarity of a solution formed by dissolving 95.8 g of LiBr (Lithium Bromide) in enough water to yield 775.6 mL of solution.
