Miss Oru Doubt:
Calculate the temporary, permanent and total hardness of water in ppm having the following composition:
Ca(HCO3)2 = 4ppm
Mg(HCO3)2 = 6ppm
CaSO4 = 8ppm
MgSO4 = 10ppm
NaHCO3 = 3ppm
Ivede NaHCO3 de atomic mass 84 alle?
Enna Answernathu 3*[100/(2*84)]
aa 2 evide ninnu vannu miss? 84 alle atomic mass?

ppm is expressed as THE MASS of particles in a unit volume of water,
ppm = mg/l.
