Sagot :
The final concentration after adding 2L of water to a 0.50 L volume of 12 M KCl is 2.4 M.
The concentration of a solute in terms of molarity is expressed as the number of moles of solute per liter of solution. The problem is regarding the dilution process of KCl. The molarity can be calculated using the dilution formula, expressed as (initial concentration of 1st solution)(initial volume)=(final concentration)(final volume). This formula shows that the number of moles remained the same throughout the process.
(12 M KCl) * ( 0.50 L) = (final concentration) ( 0.50 L + 2.0 L)
final concentration = 2.4 M KCl
