A 1.00 L sample of water contains 0.0036 g of Cl⁻ ions. Determine the concentration of chloride ions in ppm if the density of the solution is 1.00 g mL^-1. A) 2.8 ppm B) 7.2 ppm C) 3.6 ppm D) 1.8 ppm E) 5.4 ppm

Question

Quizplus · Accepted Answer

The concentration in ppm is calculated as (mass of solute in grams / mass of solution in grams) x 10^6. Here, 0.0036 g of Cl⁻ in 1.00 L of water (1000 g) gives (0.0036 / 1000) x 10^6 = 3.6 ppm.
