OlgaM077 [116]
Answer: 2mg

Part per million is unit that equal to mg/kg of water or simply 10^{-6} . In this case, you asked how much NaCl needed and know the volume of water(100mL), concentration(20ppm or 20 mg/kg) and water density.
Then, the equation would be

concentration = NaCl weight/ water weight
20 x 10^{-6} mg= NaCl weight/ (100ml x 1g/ml)
NaCl weight= 20x 10^{-6} mg/kg x 100g 
NaCl weight= 2000 x 10^{-6} g
NaCl weight= 2x 10^{-3} g = 2mg
