Molar Concentration or Molarity of solution

-Molar Concentraion
   - A homogeneous mixture one substance is dissolved in another---solution
   - The chenmical that is in the smaller quantity is called solute
                                               larger quantity is called solvent
   - Molar Concentration or Molarity is the number of moles of solute in one L of a lolution, we use M to denote molar concentration and it has the units of "mole/L"


FOMULA:  - Molarity = moles of solute(mol)/Volume of soution(L)  or  M = mol/L
       

  Ex: Calculate the molar concentration of a soluion that has 0.510 moles of NaOH in 1.400L of solution.

                               0.510mol/1.400L= 0.364M or  0.364mol/L

  Ex: Calculate the number of grams of calciumhyfroxide in 1.30L of a 0.75M Ca(OH)2 solution.
                               moles Ca(OH)2 = 0.75M  x 1.30L = 0.975mol
                               0.975mol x 74.1 = 72g
