Answer:
The solution's new volume is 1.68 L
Explanation:
Dilution is the procedure to prepare a less concentrated solution from a more concentrated one, and simply consists of adding more solvent. So, in a dilution the amount of solute does not vary, but the volume of the solvent varies.
In summary, a dilution is a lower concentration solution than the original.
The way to do the calculations in a dilution is through the expression:
Ci*Vi=Cf*Vf
where C and V are concentration and volume, respectively; and the i and f subscripts indicate initial and final respectively.
In this case, being:
- Ci= 7 M
- Vi= 0.60 L
- Cf= 2.5 M
- Vf=?
Replacing:
7 M*0.60 L= 2.5 M* Vf
Solving:
![Vf=\frac{7 M*0.60 L}{2.5 M}](https://tex.z-dn.net/?f=Vf%3D%5Cfrac%7B7%20M%2A0.60%20L%7D%7B2.5%20M%7D)
Vf= 1.68 L
<u><em>The solution's new volume is 1.68 L</em></u>
This is the balanced equation H2+Cl3 -> 2HCl.
