Question
0.915g of KHP (204.22g/mol) was dissolved
in 100ml of distilled water and titrated euth
sodium hydroxide solution. 27.55ml titrant
was needed to reach the equivalenec point.
There is 0.00448 moles of KHP present in the
sample.
a) How many moles of sodium hydroxide are
needed to neutralize each mole of KHP?
b) Therefore, how many moles of NaOH were
needed to neutralize the KHP sample?
c)What is the molar concentration (mol/L) of
the sodium hydroxide solution?
