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

  • chemistry - ,

    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

  • chemistry - ,

    so part a 0.187/35=0.005 mole Cl-
    divided by
    part b 50mls

  • chemistry - ,

    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
