25. in a titration 17ml of 0.2m naoh was used to neutralize 10ml of acetic acid (ch3 cooh) what is the molarity of the acetic acid? /

The  molarity  of  acetic  acid  is  calculated  as  follows

find  the  number  of moles  of NaOH  =  molarity  x  volume
=   17x0.2  =   3.4  moles

write  the  equation  for  reaction
  CH3COOH  +  NaOH  =  CH3COONa  +H2O

since  ratio  is be  of  CH3COOH  to  NaOH  is   1:1  the  moles  of CH3COOH   is  therefore =  3.4  moles

therefore  the  molarity  = moles/volume
=  3.4  /10  =  0.34 M

Man i dont know this answer
