Explanation:
The given data is as follows.
[tex]V_{1}[/tex] = 225.5 mL, [tex]V_{2}[/tex] = 45.00 mL
[tex]M_{1}[/tex] = 0.09988 M, [tex]M_{2}[/tex] = ?
Therefore, formula to calculate final concentration will be as follows.
[tex]M_{1}V_{1}[/tex] = [tex]M_{2}V_{2}[/tex]
Putting the given values into the above formula as follows.
[tex]M_{1}V_{1}[/tex] = [tex]M_{2}V_{2}[/tex]
[tex]0.09988 M \times 225.5 mL[/tex] = [tex]M_{2} \times 45.0 mL[/tex]
[tex]M_{2}[/tex] = 0.5 M
Thus, we can conclude that the final concentration of the given solution is 0.5 M.
The final concentration of the solution produced when 225.5 mL of 0.09988-M solution of Na2CO3 is allowed to evaporate until the solution volume is reduced to 45.00 mL is 0.5M.
HOW TO CALCULATE CONCENTRATION?
The final concentration of a solution can be calculated using the following formula:
C1V1 = C2V2
Where;
- C1 = initial concentration
- C2 = final concentration
- V1 = initial volume
- V2 = final volume
225.5 × 0.09988 = 45 × C2
22.52 = 45C2
C2 = 22.52/45
C2 = 0.5M
Therefore, the final concentration of the solution produced when 225.5 mL of 0.09988-M solution of Na2CO3 is allowed to evaporate until the solution volume is reduced to 45.00 mL is 0.5M.
