5. Calculate the molarity of a solution made from dissolving 80.Og of lithiumchloride (LiCl) in 800.OmL of solution.

Answer:M = 2.36 mol/literExplanation:1. Data:a) M = ?b) m = 80.0 g Li Clc) V = 800 ml solution2. Principles and formulae:Molarity is the unit of concentration that expresses moles of solute per liter of solution:M = moles of solute / volume of solution in litersThe number of moles, n, of a compound may be calcualted from its molar mass:n = mass in grams / molar mass3. Solution:i) Molar mass of LiCl = 42.394 g/molii) Number of moles of solute, LiCl = 80.0 g / 42.394 g/mol = 1.887 moliii) Volume of solution = 800.0 ml × 1 liter / 1,000 ml = 0.8000 literiv) M = 1.887 mol / 0.8000 liter = 2.36 M ← answer
