Solute is what gets dissovled, in this case the salt, and the solVENT is whatever a material is dissolved into, in this case the water.
Taking into account the definition of dilution, the new concentration of the solution is 0.2567 M.
First of all, you have to know that dilution is the reduction in concentration of a chemical in a solution, which is accomplished by simply adding more solvent to the solution at the same amount of solute.
In a dilution the amount of solute does not change, but as more solvent is added, the concentration of the solute decreases, as the volumeof 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= 0.385 M
- Vi= 600 mL= 0.600 L (being 1000 mL= 1 L)
- Cf= ?
- Vf= 900 mL= 0.900 L
Replacing in the definition of dilution:
0.385 M× 0.600 L= Cf× 0.900 L
Solving:
Cf= (0.385 M× 0.600 L)÷ 0.900 L
Cf= 0.2567 M
In summary, the new concentration of the solution is 0.2567 M.
