Dilution Formula:
| From: | To: |
The dilution formula \( M_f = M_i \times \frac{V_i}{V_f} \) calculates the final molarity after dilution, where a solution is mixed with additional solvent. This is fundamental in physiology and chemistry for preparing solutions of desired concentrations.
The calculator uses the dilution formula:
Where:
Explanation: The formula accounts for the conservation of moles of solute when diluting a solution, ensuring accurate concentration adjustments.
Details: Accurate dilution calculations are crucial for preparing solutions in laboratory settings, medical dosages, and physiological experiments to ensure correct concentrations for reactions and treatments.
Tips: Enter initial molarity in mol/L, initial volume in liters, and final volume in liters. All values must be valid (greater than zero).
Q1: Why is the dilution formula important in physiology?
A: It helps in preparing solutions with precise concentrations needed for experiments, treatments, and diagnostic tests, ensuring accuracy and reproducibility.
Q2: What units should I use for volume?
A: Volume should be in liters (L) for consistency with molarity (mol/L), but ensure all volume units are the same to avoid errors.
Q3: Can I use this formula for any solute?
A: Yes, the formula applies to any solute as long as the number of moles remains constant during dilution.
Q4: What if the final volume is less than the initial volume?
A: The formula assumes dilution, so final volume should be greater than initial volume. If not, it may indicate concentration, not dilution.
Q5: How does temperature affect dilution?
A: Temperature can affect volume measurements due to expansion/contraction, but the formula itself is based on mole conservation and is temperature-independent.
