Mass Per Volume Formula:
| From: | To: |
Mass per volume percentage (%w/v) is a concentration measurement that expresses the mass of solute (in grams) per 100 mL of solution. It's commonly used in chemistry, pharmacy, and biology to prepare solutions with specific concentrations.
The calculator uses the mass per volume formula:
Where:
Explanation: The formula calculates the concentration by dividing the mass of the solute by the volume of the solution and multiplying by 100 to get a percentage value.
Details: Accurate mass per volume calculations are essential for preparing solutions with precise concentrations in laboratory settings, pharmaceutical preparations, and various industrial applications where specific solution strengths are required.
Tips: Enter the mass of solute in grams and the volume of solution in milliliters. Both values must be positive numbers greater than zero for accurate calculation.
Q1: What is the difference between %w/v and %v/v?
A: %w/v (weight/volume) expresses mass per volume, while %v/v (volume/volume) expresses volume per volume. %w/v is used when the solute is a solid, while %v/v is used when both solute and solvent are liquids.
Q2: Can I use different units for mass and volume?
A: The calculator uses grams for mass and milliliters for volume. If you have different units, convert them to grams and milliliters first for accurate results.
Q3: How accurate is this calculation?
A: The calculation is mathematically precise. The accuracy depends on the precision of your mass and volume measurements in the laboratory.
Q4: When is mass per volume percentage typically used?
A: It's commonly used in pharmaceutical preparations, laboratory reagent preparation, and food industry applications where solid solutes are dissolved in liquid solvents.
Q5: Can this calculator handle very small concentrations?
A: Yes, the calculator can handle concentrations from very small to very large values, as long as the mass and volume inputs are positive numbers.
