3. A 5.0 mL sample of a stock solution of concentrated HNO3, a strong acid, is diluted with distilled water to prepare 100.0 mL of its dilute solution. A 10.0 mL sample of this dilute solution is then taken, and a pellet of sodium hydroxide, NaOH, with a mass of 250 mg is added to it. This pellet completely neutralizes the dilute acid solution. Calculate the molarity of the original stock solution of concentrated HNO3.

Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".
