Question

If 1,000.0 g of water from Luboc River contains 0.0075g of Ca²⁺ ions, how many parts per million (ppm) of calcium ions

Answer 1

PPM is a term used in chemistry to denote a very, very low concentration of a solution. One gram in 1000 ml is 1000 ppm and one thousandth of a gram (0.001g) in 1000 ml is one ppm. One thousanth of a gram is one milligram and 1000 ml is one liter, so that 1 ppm = 1 mg per liter = mg/Liter.
