Answer 2

Strictly speaking, you can't. You can only calculate its NORMALITY, i.e. the concentration of protons (or hydroxide ions) in your solution.

To see why, consider for instance 200 ml of 1 M HCl, and 200 ml of 0.5 M H2SO4. Both will contain 0.2 mol of protons which you can assess by working out how much base you've added (for instance 50 ml of 4M NaOH), but the molarity of the sulphuric acid is half that of the hydrochloric. You may also need to take account of strong and weak acids and bases, but that's a different story.

Answer 3

It is hard to answer this without a specific question or example.

assume you had an unknow concentration of HCl (hydrochloric acid) and you were titrating with a know amount of KOH (potasium ydroxide)

Since both these are univalent, you would have to put in one mole of KOH for every mole of HCL that was in the solution, before the solution would become neutral. Most titrations of this kind are titrated to neutrality. But whatever the setup, your titration tells you how many moles in the unknown sample by knowing how many moles of the known concentration titrant it took to get to the end point.

You know the moles of the HCl in the unknown sample, and you know the volume of the unknown sample so you can easily express that in moles/volume or moles/liter and that is molarity.

hope that was helpful

Answer 4

Concentration of Acid x Volume of Acid = Concentration of Base x Volume of Base

Answer 5

Usinf the formula
m1v1=m2v2
where mis molarity and v is the volume

Answer 6

apply the molarity formula or find it from chemestry book of 11th std.
