0.1% w/v Formula:
| From: | To: |
A 0.1% w/v (weight/volume) solution contains 0.1 grams of solute per 100 mL of solution. This is a common concentration used in various scientific, medical, and laboratory applications.
The calculator uses the formula:
Where:
Explanation: The factor 0.001 comes from 0.1% which equals 0.1g/100mL = 0.001g/mL.
Details: Precise concentration preparation is crucial for scientific experiments, medical treatments, and quality control in various industries where even small variations can significantly impact results.
Tips: Enter the desired volume in milliliters. The calculator will determine the mass of solute needed to create a 0.1% w/v solution.
Q1: What does w/v stand for?
A: w/v stands for "weight/volume" and indicates the mass of solute (in grams) per volume of solution (in milliliters).
Q2: Can I use this for different percentage solutions?
A: No, this calculator is specifically designed for 0.1% w/v solutions. For other concentrations, you would need to adjust the formula.
Q3: Is temperature considered in this calculation?
A: No, this calculation assumes standard conditions. For precise work, temperature effects on density should be considered.
Q4: How accurate should my measurements be?
A: For most applications, analytical balance measurements to 0.0001g and volumetric flasks are recommended for precise preparation.
Q5: Can this be used for solid or liquid solutes?
A: This calculator works for both solid and liquid solutes, as long as you're measuring by mass. For liquids, you may need to convert from volume to mass using density.
