Draw a bar diagram on your sketch paper based on the table below and determine the non-carbon
hardness (permanent hardness) in mg/L of CaCO3.
Atomic weight
Equivalent weight
or molecular
Concentration (mg/L)
meq/L concentration
(mg/meq)
weight (g/mol)
100
Ca2+
40
150 mg/L as CaCO3
150/50=3
(g/mol)/2(eq/mol)=50
Mg2+
24
100 mg/L as CaCO3
100/50=2

72 mg/L
35.5
71 mg/L
O 25 mg/L of CaCO3
O 50 mg/L of CaCO3
O 100 mg/L of CaCO3
O 150 mg/L of CaCO3
