When a solution labeled 0.50 m hno3 is diluted with water to give 0.25 m hno3, what happens to the number of moles of hno3 in the new solution?

Answer;

The number of moles remains constant.

Explanation;

-A dilution is a solution made by adding more solvent to a more concentrated solution (stock solution), which reduces the concentration of the solute.

-To dilute a stock solution, the following dilution equation is used:

   M1 V1 = M2 V2.     where; M1 and V1 are the molarity and volume of the concentrated stock solution, and M2 and V2 are the molarity and volume of the diluted solution you want to make.

-The process of dilution keeps the amount of solute constant, but increases the total amount of solution, thereby decreasing its final concentration.
