Asolution is prepared by diluting 50.00 ml of 2.575 m solution of hno3 to 250.0 ml. what is the molarity of the resulting solution?

Explanation:

Hello,

In this case, since the dilution process does not affect the quantity of moles in the solution (from state 1 to 2), one leverages the aforesaid conservation and subsequently uses the definition of molarity to obtain the dilution formula as shown below:

Next, solving for the molarity after the dilution, , one obtains:

Best regards.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
