Which unit is especially useful for very dilute solutions?

Answer and explanation

Correct answer: ppm

For trace amounts of solute, such as tiny impurity or pollutant levels, percentage values may be inconveniently small. Parts per million (ppm) expresses the number of solute parts in one million parts of sample and is therefore useful for very dilute solutions. The other terms are also valid but less convenient here.
