Hello Chegg family i have a few titration and oxidation problems. Thank You!

1.) What volume of a 0.367 M hydrochloric acid solution is required to neutralize 14.3 mL of a 0.177 Msodium hydroxide solution?
??mL hydrochloric acid

What volume of a 0.142 M barium hydroxide solution is required to neutralize 24.1 mL of a 0.154 Mperchloric acid solution?
??mL barium hydroxide

2.) An aqueous solution of hydrochloric acid is standardized by titration with a 0.177 M solution of calcium hydroxide.
If 14.3 mL of base are required to neutralize 27.8 mL of the acid, what is the molarity of the hydrochloric acid solution?
??M hydrochloric acid

An aqueous solution of barium hydroxide is standardized by titration with a 0.142 M solution of perchloric acid.
If 24.1 mL of base are required to neutralize 13.6 mL of the acid, what is the molarity of the barium hydroxide solution?
??M barium hydroxide

3.) Potassium hydrogen phthalate is a solid, monoprotic acid frequently used in the laboratory as aprimary standard. It has the unwieldy formula of KHC8H4O4. This is often written in shorthand notation as KHP.
If 37.5 mL of a sodium hydroxide solution are needed to neutralize 0.957 grams of KHP, what is the molarity of the sodium hydroxide solution?
??M
