How this calculator works
Enter the values for first value, second value and review the units before calculating.
Formula / method
C1V1 = C2V2; C2 = C1V1 ÷ V2
Worked example
0.25 L of 2 M stock diluted to 1 L gives 0.5 M final concentration.
Assumptions and limitations
Solute amount is conserved and volumes are compatible for the approximation.
Volume contraction, reaction, heat and activity effects are ignored.
