Answer 1

Calculation of the Mass of the Formed Salt

To calculate the mass of the formed salt, we need to determine the stoichiometry of the reaction between the 20% sodium hydroxide (NaOH) solution and the nitric acid (HNO3) in a stoichiometric ratio.

Unfortunately, the provided search results do not directly provide the stoichiometric ratio or the molar masses of the compounds involved. Therefore, I am unable to provide a specific calculation for the mass of the formed salt.

However, I can guide you through the general steps to calculate the mass of the formed salt once you have the stoichiometric ratio and the molar masses of the compounds involved.

1. Determine the balanced chemical equation for the reaction between sodium hydroxide and nitric acid. 2. Identify the stoichiometric ratio between the reactants and the product. This ratio is based on the coefficients in the balanced equation. 3. Determine the molar masses of sodium hydroxide, nitric acid, and the salt formed. 4. Use the stoichiometric ratio and the molar masses to calculate the moles of the reactants and the product. 5. Finally, calculate the mass of the formed salt using the moles and the molar mass of the salt.

Please provide the balanced chemical equation and the molar masses of the compounds involved, and I will be happy to assist you further in calculating the mass of the formed salt.
