Concentration Formula:
| From: | To: |
The concentration formula C = n/V calculates the molar concentration of a solution, where C is the concentration in moles per liter (mol/L), n is the amount of substance in moles, and V is the volume in liters. This fundamental relationship is essential in chemistry for preparing solutions and analyzing chemical reactions.
The calculator uses the concentration formula:
Where:
Explanation: This formula expresses the relationship between the amount of solute and the volume of solution, providing the concentration in standard molar units.
Details: Accurate concentration calculations are crucial for preparing chemical solutions, conducting experiments, pharmaceutical formulations, and industrial processes where precise concentrations are required for proper chemical reactions and biological activities.
Tips: Enter the amount of substance in moles and the volume in liters. Both values must be positive numbers greater than zero. The calculator will compute the concentration in mol/L.
Q1: What is molar concentration?
A: Molar concentration (molarity) is the number of moles of solute per liter of solution, expressed in mol/L or M.
Q2: How do I convert grams to moles?
A: Use the formula: moles = mass (g) / molar mass (g/mol). You need to know the molar mass of the substance.
Q3: Can I use different volume units?
A: Yes, but you must convert to liters first. Common conversions: 1 mL = 0.001 L, 1 dL = 0.1 L.
Q4: What is the difference between concentration and molarity?
A: Molarity is a specific type of concentration that uses moles per liter. Concentration can also be expressed in other units like mass/volume or percentage.
Q5: When is this formula not applicable?
A: This formula assumes ideal solutions and may not account for temperature effects, density changes, or non-ideal behavior in concentrated solutions.
