Solutions

Expert Solution

HNO3(aq) + KOH (aq)--------------------> KNO3(aq) + H2O(l)

1 mole       1 mole

HNO3                                                          KOH

M1 =                                                          M2 = 0.16M

V1 = 17.85ml                                             V2 = 16ml

n1 = 1                                                          n2 = 1

                 M1V1/n1     =    M2V2/n2

                     M1         =    M2V2n1/V1n2

                                   = 0.16*16*1/17.85*1

                                  = 0.1434M

molarity of HNO3   = 0.1434M >>>>answer
