1. What is Molarity of Mixed Solutions?

The molarity of mixed solutions calculation determines the final concentration when two solutions are combined. It's based on the principle of conservation of moles, where the total number of moles remains constant but the volume changes.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( M_{final} \) — Final molarity (mol/L)
• \( n_1 \) — Moles from solution 1 (mol)
• \( n_2 \) — Moles from solution 2 (mol)
• \( V_{total} \) — Total volume after mixing (L)

Explanation: This formula calculates the concentration of the resulting solution by dividing the total number of moles by the total volume.

3. Importance of Molarity Calculation

Details: Accurate molarity calculation is essential for preparing solutions with specific concentrations, chemical reactions, laboratory experiments, and industrial processes where precise concentrations are required.

4. Using the Calculator

Tips: Enter the moles from each solution and the total volume after mixing. All values must be positive numbers, and total volume must be greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What if the solutions have different solvents?
A: This calculation assumes ideal mixing behavior and that the solvents are compatible. For different solvents, volume changes may occur, and more complex calculations are needed.

Q2: Can I use this for more than two solutions?
A: Yes, simply sum the moles from all solutions and divide by the total volume: \( M_{final} = \frac{\sum n_i}{V_{total}} \)

Q3: What units should I use?
A: Moles should be in mol and volume in liters (L) to get molarity in mol/L.

Q4: Does temperature affect the calculation?
A: Volume measurements should be made at the same temperature, or appropriate corrections should be applied for temperature-dependent volume changes.

Q5: What if volume contraction or expansion occurs?
A: For non-ideal solutions where volume isn't additive, measured total volume should be used rather than summing individual volumes.
