Volume of HCl, mL:26.5mL
Volume of NaOH,mL:29.1mL
Molarity of NaOH, mol/L:0.1m/L
balanced equation: NaOh+HCl>NaCl+H2O
Using the above equation calculate the number of moles of acid required to react with 2.91 moles of base.
Please help me I have no idea what to do.

Just use the definition. What is molarity? It is M = moles/L.
So plug in L and M and you can calculate mols. Or you can rearrange the M = mols/L to M x L = mols. Just apply what you know and this stuff won't get the best of you. Have fun. 
Look, why don't you guys just come out with the answer and then explain how you got it instead of leaving it up for the other person to figure it out.
