Mass Volume Percent Formula:
| From: | To: |
Mass volume percent (% m/v) is a way of expressing the concentration of a solution. It represents the mass of the solute (in grams) present in 100 mL of solution. This concentration unit is commonly used in chemistry and biology for preparing solutions.
The calculator uses the mass volume percent formula:
Where:
Explanation: The formula calculates what percentage of the solution's volume is made up by the solute's mass.
Details: Mass volume percent is crucial for preparing accurate solutions in laboratories, medical settings, and industrial applications. It ensures consistent concentrations for experiments, medications, and chemical processes.
Tips: Enter the mass of solute in grams and volume of solution in milliliters. Both values must be positive numbers. The calculator will compute the mass volume percentage concentration.
Q1: What's the difference between % m/v and % w/v?
A: They are essentially the same - both represent weight (mass) in grams per 100 mL of solution. The notation % w/v (weight/volume) is sometimes used interchangeably with % m/v.
Q2: When should I use mass volume percent?
A: Use it when you need to express concentration based on the mass of solid solute dissolved in a liquid solution, particularly in biological and medical applications.
Q3: How does temperature affect % m/v?
A: Since volume can change with temperature while mass stays constant, % m/v values are temperature-dependent. For precise work, specify the temperature.
Q4: Can I use other units besides grams and mL?
A: The standard is grams and mL, but you can use other units as long as you maintain mass/volume relationship (e.g., mg/mL would give the same value as g/L).
Q5: How accurate is this calculation?
A: The calculation is mathematically exact. Accuracy depends on your measurements of mass and volume.
