Percentage solutions
The concentration of a solution may be expressed on the basis of weight per unit volume (w/v) or volume per unit volume (v/v).
% w/v = number of grams of a substance in 100 ml of a liquid
% v/v = number of ml of a substance in 100 ml of liquid
| % Solution | g or ml/100 ml | mg/ml | Solution strength |
|---|---|---|---|
| 100 | 100 | 1000 | 1:1 |
| 10 | 10 | 100 | 1:10 |
| 1 | 1 | 10 | 1:100 |
