1. What is the Moles Volume Concentration Formula?

Definition: This calculator computes the amount of substance (moles) based on concentration and volume using the formula n = c × V.

Purpose: It helps chemistry students and professionals quickly determine the number of moles in a solution when concentration and volume are known.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( n \) — Amount of substance (moles)
• \( c \) — Concentration (mol/dm³)
• \( V \) — Volume (dm³)

Explanation: The concentration is multiplied by the volume to calculate the number of moles of solute in the solution.

3. Importance of Moles Calculation

Details: Accurate mole calculations are essential for preparing solutions, conducting chemical reactions, and stoichiometric calculations in chemistry.

4. Using the Calculator

Tips: Enter the concentration in mol/dm³ and volume in dm³. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for concentration?
A: The calculator uses mol/dm³ (moles per cubic decimeter), which is equivalent to molarity (M).

Q2: Can I use different volume units?
A: The calculator expects dm³. Convert other units first (1 L = 1 dm³, 1000 cm³ = 1 dm³).

Q3: What if my concentration is in g/dm³?
A: First convert mass concentration to molar concentration by dividing by the molar mass of the solute.

Q4: Does this work for gases?
A: For gases at standard conditions, you can use molar volume (22.4 dm³/mol at STP).

Q5: How precise are the results?
A: Results are displayed to 3 decimal places, but actual precision depends on your input values.
