What is the molarity of a solution prepared by dissolving 21.4 g of Ca(NO3)2 into 325 mL of water?

Molarity is the number of moles per liter. So find the number of moles by dividing 14.75 by the mol. Wt.

Of calcium chloride, which has the molecular formula: CaCl2. Mol wt. Ca = 40 Mol wt.

Cl = 35.5 Mol wt. CaCl2 = 40 + 2*35.5 = 111 g/mol Now can you get it?

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
