What is the molarity of the Cl ion in the solution of a sample containing 0.187g Cl dissolved in 50.0 ml water?

use your conversion factors to determine grams to mols and then use mols of cl per solution to convert

thanks

part a) 0.187/35.453 = 5.27 x 10^4 moles of Cl
part b) 50 ml = .05 l
part a divided by part b = 1.05 x 10^2 M 
so part a 0.187/35=0.005 mole Cl
divided by
part b 50mls 
0.187/35.453 = 0.00527 (the above answer should be x 10^3).
0.00527/0.05 L = 0.105 M. (above should be x 10^1). 
thanks your great
