Taking into accoun the definitio of dilution, if 0.250 L of a 6.00 M HNO₃ solution is diluted to 2.00 L, the molarity of the new solution is 0.75 M.
First of all, you have to know that dilution is the reduction of concentration of a chemical substance in a solution and consists of lowering the amount of solute per unit volume of solution.
In other words, dilution is the procedure followed to prepare a less concentrated solution from a more concentrated one by simply adding more solvent to the solution.
In a dilution the amount of solute does not change, but as more solvent is added, the concentration of the solute decreases, as the volume (and weight) of the solution increases.
A dilution is mathematically expressed as:
Ci×Vi = Cf×Vf
where
- Ci: initial concentration
- Vi: initial volume
- Cf: final concentration
- Vf: final volume
In this case, you know:
- Ci= 6 M
- Vi= 0.250 L
- Cf= ?
- Vf= 2 L
Replacing in the definition of dilution:
6 M × 0.250 L= Cf × 2 L
Solving:
[tex]Cf=\frac{6 Mx0.250 L}{2 L}[/tex]
Cf=0.75 M
In summary, if 0.250 L of a 6.00 M HNO₃ solution is diluted to 2.00 L, the molarity of the new solution is 0.75 M.
