Answer:
The resulting NaCl solution has a concentration of 0.4732 M
Explanation:
Concentration is the ratio of amount of solute present in a solution to the amount of solvent or total solution. Morality is the commonly used unit of concentration.
[tex]Concentration=\frac{(\text{Moles of solute})}{(\text{Volume of solution})}[/tex]
Since we are given with same NaCl solution, we have
[tex]\frac{(M_1 V_1+M_2 V_2)}{(V_1+V_2 ) }[/tex]....................(1)
Where
[tex]M_1= 0.690 m[/tex]
[tex]V_1= 309 ml[/tex]
[tex]M_2= 0.330 m[/tex]
[tex]V_2= 467 ml[/tex]
Now substituting the values in equation in (1)
=>[tex]\frac{( (0.690\times 309 )+(0.330\times 467))}{(309+467) }[/tex]
=>[tex]\frac{ (213.21\times 154.11)}{776}[/tex]
=>[tex]\frac{367.32}{776}[/tex]
=>0.4732 M
