6. If the pH is 12.2 what was the initial concentration of the base? _____ Weak Bases dissociate very similar to weak acids. The concentration of OH- is not equal to the original concentration of the base. You must determine the amount of dissociation. All bases can be put into a general form of equation BOH ( …

Concentration Units. molarity (M) moles of solute / liter of solution (most commonly used unit of concentration) molality (m) moles of solute / kg of solvent . Compare to molarity and notice differences in the denominator. (L vs kg; solution vs. solvent) Molality is independent of temperature so it is used for calculating boiling point elevation

(Hint: Use the density and molar mass of water.) What happens to the concentration of water when a solute is dissolved in it? (1000 g/L) / 18.0 g/mol = 55.6 mol/L. The concentration of water decreases as a the concentration of a solute increases because the solute occupies some of the volume and the water molecules are pushed apart. 4

When you are calculating the concentration of a solution, you must do so by calculating the number of moles of solute dissolved into the total volume of solution. Example 1: Molar mass of salt (NaCl) is 58.5 g/mol, so if you dissolve 58.5g of salt in enough water to make 1.00 liter of solution, you have one mole of solute dissolved per liter of ...
