Chem 105, Please help! super confused and lost on these!

  1. Calculate the volume of 0.550-M NaOH solution needed to completely neutralize 98.3 mL of a 0.630-M solution of the monoprotic acid HNO3.
  2. 80.96 mL of a solution of the acid H2C2O4 is titrated, and 64.30 mL of 0.8600-M NaOH is required to reach the equivalence point. Calculate the original concentration of the acid solution.
  3. A 50.00-mL sample of aqueous Ca(OH)2 requires 34.66 mL of 0.859 M nitric acid for neutralization. Calculate the concentration (molarity) of the original solution of calcium hydroxide.
  4. What volume (mL) of 0.250 M HNO3 is required to titrate (neutralize) a solution containing 0.266 g of KOH?
