How many ml of 0.01-m naoh will be required to titrate 0.061-g of khp to it's endpoint?

The volume of NaOH needed for the titration is calculated by equating the number of moles of KHP and NAOH.

(1) number of moles of KHP:
         n = mass of KHP / molar mass of KHP
Substituting,
         n = 0.061 g / (204.22 g/mol) = 2.987 x 10⁻⁴ moles KHP

(2) number of moles of NaOH
         n = (volume NaOH in L)(molarity of NaOH)
          n = V x 0.01

Equating,
       0.01V = 2.987 x 10⁻⁴

The value of V from the equation is 0.0299L of NaOH. 

Converting the value to mL will give us the answer of 29.87 mL. 

Idk the answer imthink snail cant mate they dont lol

Remember that rust prevented by placing a sacrificial electrode in electrical contact with the iron. the sacrificial electrode must be composed of a metal that  oxidizes  more easily than iron (that is, it must be below iron in table 18.1).
