What volume of a 0.986 M solution of NaOh must be added to 26.5 ml of 0.581 M hcl to completely neutralize the acid
How many moles of NaOh are needed for the neutralization?

Is this a homework exercise? Isn't there a reason you should do this yourself?

LOL i agree with steve...its really too easy to sweat about.
however, to neutralize the solution:
NaOH + HCl----> NaCl +HOH is balanced, so 1 mole of NaOH will neutralize 1 mole of HCl.
Calculate the moles of HCl you have: and then calculate the volume of 0,986 NaOh you need to balance them according to the above relationship.

NaOH + HCl --> H2O + NaCl
1 mole of NaOH reacts with 1 mole of HCl
molarity x liters = moles
You can use this info to solve the problem.
