1. What is the Volume Formula?

The volume formula \( V = \frac{n}{M} \) calculates the volume of a solution in liters when you know the amount of substance (in moles) and the molarity (in moles per liter).

2. How Does the Calculator Work?

The calculator uses the volume formula:

Where:

• \( V \) — Volume in liters (L)
• \( n \) — Amount of substance in moles (mol)
• \( M \) — Molarity in moles per liter (mol/L)

Explanation: This formula is derived from the definition of molarity, which is moles of solute per liter of solution.

3. Importance of Volume Calculation

Details: Calculating volume from moles and molarity is essential in chemistry for preparing solutions with specific concentrations, which is crucial for experiments, industrial processes, and medical applications.

4. Using the Calculator

Tips: Enter the amount of substance in moles and the molarity in mol/L. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is molarity?
A: Molarity (M) is a measure of concentration defined as the number of moles of solute per liter of solution.

Q2: Can this formula be used for any solution?
A: Yes, this formula applies to any solution where you know the amount of solute in moles and the molar concentration.

Q3: What if I have the concentration in other units?
A: You'll need to convert to mol/L first. For example, mmol/L needs to be divided by 1000 to get mol/L.

Q4: How precise should my measurements be?
A: The precision depends on your application. For most laboratory work, 4 significant figures is typically sufficient.

Q5: Can I calculate moles if I know volume and molarity?
A: Yes, you can rearrange the formula to \( n = M \times V \) to find the amount of substance.
