Question:

If you take an 11.5 mL sample of a 12.6 M {eq}NH_3 {/eq} solution and dilute it to a total volume of 0.650 L, what will be the concentration of the final solution?

Dilution of Solution:

The concentration of a solute species in a solution is often defined using a molarity value. It represents a number of solute moles dissolved per liter volume of the prepared solution. It can be calculated from a ratio of solute molar quantity and solution volume values. The solution volume can be increased without increasing the solute molar quantity dissolved within. This occurs through dilution by adding more of the pure liquid solvent. The solute molarity will be lower in the diluted solution relative to the starting stock solution.
