Question
How do i determine molarity using ppm?
There are two methods:
1. At low concentration water solutions (<1000 ppm), ppm is equal to mg/L. Just change mg to gram to moles.
2. At any concentration ppm is equal to mg/kg. Kg is not a volume so you have to multiple by the density of the solution.
mg/kg X 1 kg/ 1000 g = mg/g X g/mL = mg/mL X 1000 mL/L = mg/L, then do #1 above.
Just do the conversion step by step starting with mg/L or mg/kg.
