Hey super smart chemistry people :D please help me with one tiny little problem? The question is:Calculate the molarity of 1.60 L of a solution containing 1.55g of dissolved KBr. I have been trying to figure this out but I dont know where to start....

Question

anonymous · Answer

DIvide the mass of KBr by the molecular weight, that's the number of KBr ion-pairs you dissolved, in moles.

Divide the number of moles by the volume, that's the molarity, in moles per liter. 

would you like to try it out here?

Umm sure?

anonymous · Answer

@monet212 Try this formula:
$$Molarity (M)=\frac{solute (Moles) }{solvent (Liters) }$$

@monet212 answered it in your last question: http://openstudy.com/study#/updates/51749a79e4b0050fabb96202
