The concentration of Ca(HCO3)2 in a sample of hard water is 500 ppm
The density of water sample is 1 0 gm/ml calculate the molarity of
solution

Dear Student,

The computation are expressed below,

Hardness = 500 ppm = 500 mglt = 0
5 gmltρ = 1
0 gmmlMolar mass of Ca(HCO3)2 = 162
112 gmmolMolality = 0 5 gmlt162
112 gmmol=0 0031 M
