5. calculate the molarity of a solution made from dissolving 80.og of lithium
chloride (licl) in 800.oml of solution.

Explanation:

1. Data:

a) M = ?

b) m = 80.0 g Li Cl

c) V = 800 ml solution

2. Principles and formulae:

Molarity is the unit of concentration that expresses moles of solute per liter of solution:

The number of moles, n, of a compound may be calcualted from its molar mass:

3. Solution:

i) Molar mass of LiCl = 42.394 g/mol

ii) Number of moles of solute, LiCl = 80.0 g / 42.394 g/mol = 1.887 mol

iii) Volume of solution = 800.0 ml × 1 liter / 1,000 ml = 0.8000 liter

iv) M = 1.887 mol / 0.8000 liter = 2.36 M ← answer

the answer is 48m^2!
