What is the concentration of ammonia in a solution if 20.90ml of a 0.1110 M solution of HCl are needed to titrate a 100.0ml sample of a solution?

Solutions

Expert Solution

NH3   +    HCl-----> NH4Cl

1 mole    1 mole

HCl                                                                          NH3

M1 = 0.111M                                                       M2 =

volume = 20.9ml                                                  V2 = 100ml

no of molesn1 = 1                                                no of moles n2 = 1

M1V1/n1   = M2V2/n2

M2      = M1V1n2/n1V2

       = 0.111*20.9*1/1*100 = 0.0232 M >>>> answer
