What will be the final concentration of the solution indicated that will result from the following dilutions?
a. 14.0ml of a 4.2M NaCO3 solution is diluted to 86.0ml.
b. 450ml of a 1.22M HCl solution is diluted to 1.26 L.
c. 25.0 L of a 0.076M H2SO4 solution is diluted to 82.0ml.
d. 1.32 L of a 6.4M NaOH solution is diluted to 15.6 L.
e. 2.60 L of a 4.07M KOH solution is diluted to 5.2 gallon.
Final Concentration of Solutions
After applying the dilution concentration formula M1V1 = M2V2, the final concentrations for the given scenarios are:
a. Final concentration is 0.68M
b. Final concentration is 0.44M
c. Final concentration is 23.17M
d. Final concentration is 0.54M
e. Final concentration is 0.54M
The concept of dilution in chemistry is crucial for achieving desired concentrations of solutions. By utilizing the formula M1V1 = M2V2, we can accurately determine the final concentration after dilution. In the scenarios provided:
a. For scenario a, diluting 14.0ml of a 4.2M NaCO3 solution to 86.0ml results in a final concentration of 0.68M. b. Scenario b involves diluting 450ml of a 1.22M HCl solution to 1.26 L, yielding a final concentration of 0.44M. c. Diluting 25.0 L of a 0.076M H2SO4 solution to 82.0ml leads to a final concentration of 23.17M in scenario c. d. Scenario d consists of diluting 1.32 L of a 6.4M NaOH solution to 15.6 L, resulting in a final concentration of 0.54M. e. Lastly, diluting 2.60 L of a 4.07M KOH solution to 5.2 gallons gives a final concentration of 0.54M in scenario e.To delve deeper into dilution and concentration calculations, it's important to understand the relationship between volume and concentration, as demonstrated in these scenarios.
