![### Understanding Percentage Mass/Volume (% m/V)
**Question 7: The definition of % m/V is _____**
- [ ] grams solute/mL solution x 100
- [x] grams solution/mL solute x 100
- [ ] mL solute/grams solution x 100
- [ ] mL solution/grams solute x 100
**Explanation:**
The correct definition of percentage mass/volume (% m/V) is crucial in various scientific calculations, including chemistry and biology. % m/V is used to express the concentration of a solution. This specific concentration measure tells us how many grams of a solute are present per 100 mL of the solution.
**Correct Answer:**
The correct definition is:
- grams solution/mL solute x 100
This answer highlights that to calculate % m/V, you need to know the mass of the solute in grams and the volume of the solution in milliliters. Multiplying this ratio by 100 gives you the percentage concentration.
