First Enter the PPM … 2 ppm = 2 mg dye / L of solution. 2a) Using 0.002 g/L, caculate the molarity: 0.002 g/L divided by 327 g/mol = 6.1 x 10-6 M. 2b) Using 2 mg/L, calculate the molarity 2 mg/L divided by 327,000 mg/mol = 6.1 x 10-6 M. You might want to go back to problem #1 and try out 78 mg/L with the atomic weight of calcium ion expressed as mg/mol instead of g/mol. 2018-11-06 The HI96771 has a unique chemistry that allows for the measurement of samples with chlorine concentrations up to 500 mg/L (ppm) without having to perform a dilution. This portable photometer features an advanced optical system; the combination of a special tungsten lamp, a narrow band interference filter, and silicon photodetector ensure accurate photometric readings every time.

500 ppm to mg l

ppm↔mg/mL 1 mg/mL = 1000 ppm. ppm↔mg/tsp 1 mg/tsp = 5000 ppm. ppm↔ug/uL 1 ug/uL = 1000 ppm. ppm↔pg/uL 1 ppm = 1000 pg/uL.
