Dear Student,
 
Question statement is: If the concentration of Ca+ ions in a water sample is 0.0002M. then what is the concentration of Ca+ ions in the solution in ppm (parts per million)?
 
Solution: 
1 ppm = 1 mg / L
Molar mass of Ca+ ion = 40 g/mol
Given, Molar concemtration = 0.0002 M
 
Mass of Ca+ ions in litre = (40 g /mol) × 0.0002 M
                                    = 0.008 g / L = 8 mg / L =  8 ppm of Ca+ ion solution.
