Volume Calculation Formula:
From: | To: |
This calculator converts between grams per mole (molecular weight) to milliliters (volume) using molarity. It's particularly useful in chemistry for preparing solutions with specific concentrations.
The calculator uses the following equation:
Where:
Explanation: The equation calculates the volume of solution needed to achieve a specific molar concentration given the mass of solute and its molecular weight.
Details: Accurate volume calculations are essential for preparing chemical solutions with precise concentrations, which is critical in laboratory work, pharmaceutical preparations, and chemical manufacturing.
Tips: Enter the mass in grams, molarity in mol/L, and molecular weight in g/mol. All values must be positive numbers.
Q1: Why divide by 1000 in the formula?
A: The division by 1000 converts liters to milliliters, giving the final volume in mL.
Q2: Can I use this for any chemical compound?
A: Yes, as long as you know the exact molecular weight of the compound and it dissolves completely in the solvent.
Q3: Does this account for solution density?
A: This calculation assumes ideal behavior and doesn't account for density changes in concentrated solutions.
Q4: What if my compound is a hydrate?
A: For hydrates, include the water molecules in the molecular weight calculation (e.g., CuSO₄·5H₂O).
Q5: How precise should my measurements be?
A: For most laboratory work, measure mass to at least 3-4 significant figures for accurate results.
