Solution

part-A

   0.1KNO3

KNO3 (aq)------------------> K^+ (aq) + NO3^- (aq)

0.1M                                                    0.1M

[NO3^-]   = [KNO3}

[NO3^-]   = 0.1M

The molarity of NO3^- is 0.1M

   [NO3^-]   = 0.1M

part-B

0.27M Ca(NO3)2

Ca(NO3)2 (aq) ----------------------> Ca^2+ (aq) + 2 NO3^- (aq)

0.27M                                                                   2*0.27M

   [NO3^-]    = 2[Ca(NO3)2]

                    = 2*0.27   = 0.54M

The molarity of NO3^- = 0.54M

         [NO3^-]   = 0.54M

part-C

   0.32M Al(NO3)3

       Al(NO3)3 ---------------------> Al^3+ (aq) + 3No3^- (aq)

      0.32M                                                       3*0.32M

          [NO3^-]   = 3*[Al(NO3)3]

          [NO3^-]    = 3*0.32M = 0.96M

The molarity of NO3^-   = 0.96M

    [NO3^-]   = 0.96M
