Concentration vs Mass of Solute
公式
## How to Calculate PPM ### Formula **ppm = mass of solute (mg) / mass of solution (kg)** Equivalent to mg/L for dilute aqueous solutions. 1 ppm = 1 part per 1,000,000 parts.
计算示例
5 mg of fluoride in 1 kg of water.
- 01ppm = 5 mg / 1 kg
- 02ppm = 5 ppm
常见问题
What does ppm stand for?
Parts per million. It represents one unit of solute per one million units of solution.
How do you convert ppm to percent?
Divide by 10,000. For example, 5000 ppm = 0.5%.
Is ppm the same as mg/L?
For dilute aqueous solutions at room temperature (density ~1 kg/L), ppm and mg/L are essentially equivalent.
