How many milliliters of 0.167 m hclo4 solution are needed to neutralize 50.00 ml of 0.0832 m naoh?
VashaNatasha [74]
HClO4   +NaOH   ----->  NaClO4  +  H2O
moles  of  NaOH =  (0.0832  x  50 ) /1000=  4.16 x10^-3  moles
since  the  mole  ratio  of  HClO4  to  NaOH  is  1:1   the  moles  of  HClO4  is also  4.16  x  10^-3  moles

volume  of   HClO4  is therefore =  moles/ molarity
  that  is   4.16  x  10^-3mol/  0.167 mol/L=  0.0249L
multiply  by  1000  to  convert  to  ml
0.0249  x 1000=  24.9  ml
