Molarity Formula:
From: | To: |
Molarity (M) is a measure of the concentration of a solute in a solution, defined as the number of moles of solute per liter of solution. It is one of the most commonly used units in chemistry for quantifying concentration.
The calculator uses the molarity formula:
Where:
Explanation: The formula calculates the number of moles of solute (mass divided by molar mass) and then divides by the volume of the solution to obtain concentration.
Details: Accurate molarity calculation is essential for preparing chemical solutions, conducting experiments, and understanding reaction stoichiometry in chemistry and biochemistry.
Tips: Enter mass in grams, molar mass in g/mol, and volume in liters. All values must be positive numbers greater than zero.
Q1: What's the difference between molarity and molality?
A: Molarity is moles per liter of solution, while molality is moles per kilogram of solvent. Molarity is temperature-dependent, while molality is not.
Q2: How do I convert mass to moles?
A: Use the formula: moles = mass (g) / molar mass (g/mol). This calculator performs this conversion as part of the molarity calculation.
Q3: What are typical molarity values?
A: Concentrations range from very dilute (0.001 M) to concentrated (10+ M), depending on the solute and application.
Q4: Why is molar mass important?
A: Molar mass converts between mass and moles, which is fundamental to all stoichiometric calculations in chemistry.
Q5: Can I use different volume units?
A: The calculator requires liters. Convert milliliters to liters by dividing by 1000 (1 mL = 0.001 L).
