When 45.0g cacl2 is dissolved to make a 750.ml solution what is the resulting molarity. show work

Molarity is the method of expressing concentration of solution. Mathematically, it is expressed as
Molarity = 

In present case, Molecular weight of CaCl2 = 110.98 g
volume of solution = 750 ml = 0.750 l
weight of solute (CaCl2) = 45 g

∴Molarity = 
                = 0.54 M

Concentration of solution is 0.54 M

Well to my expert knowledge and my exquisite calculations i think the the negative ion # 412 is the key to sucess

Since there is the same amount of agn03 in both silver chloride and silver nitrate they produce the same amount of moles. therefore silver chloride produces the same amount of silver nitrate, so your answer is 15.0 moles of silver nitrate. i hope this !
