The concentration of HClO4 is calculated as follows
write the equation for the reaction
NaOH + NClO4 = Na ClO4 + H2O
find the moles of NaOh that is moles = molarity x volume /1000
= 22.62ml x 0.200 /1000 = 4.524 x10^-3 moles
by use of mole ratio between NaOh to HClO4 which is 1:1 the moles of HClO4 is= 4.524 x10 ^-3 moles
concentration = moles /volume x1000
= (4.524 x10^-3)/25 x1000 = 0.18 M

Answer: Balanced chemical equation will be :

Explanation:
(Unbalanced)
A balanced chemical reaction follows the Law of Conservation of Mass. which states in a chemical reaction mass can neither be created nor be destroyed. In other words total mass of the products is equal to the total mass of reactants.
Balanced chemical equation will be :
