The long way but it always works.
Write the equation and balance it.
HCl + NaOH -->NaCl + H2O
moles KOH = M x L = 5M xs 0.002L = ??
Using the coefficients in the balanced equation, convert moles KOH to moles HCl. You can see that the ratio of HCl to KOH is 1:1 in the equation; therefore, moles HCl = moles KOH.
Now moles HCl = M x L
You know moles HCl and M, solve for L and convert to mL.
