Frequently asked questions

What does w/v percent mean?
Weight/volume percent (w/v %) is the mass of solute (g) per 100 mL of solution. A 5% NaCl solution has 5 g of NaCl in every 100 mL.
How do I convert between ppm and g/L?
1 g/L = 1000 mg/L = 1000 ppm (in dilute aqueous solutions where 1 L ā‰ˆ 1 kg).
