Mass of solute = 0.101 g of calcium

Mass of solvent = 650 g of water

ppm = mass of solute in mg / mass of solvent in Kg

1 g ----- 1000 mg
0.101 g --- ?

mass of solute = 0.101 * 1000 = 101 mg

1 kg ----- 1000 g
? -------- 650 g

mass of solvent = 650 / 1000 = 0,65 Kg

ppm = 101 / 0,65

= 155.38 ppm

hope this helps!
