Question

Which of the following are correct equivalent values ?
For any solutions specified, assume they have the density ofwater. There may be more than one correct.
a) 0.050 mg/L = 50 ppm b) 3.0 ppm = 3.0 g solute / 106 gsolution c) 25 g/L = a weight percent of 0.25 d) 25 ppm = 2.5 × 105 g solute/ 1 g solution e) 3.0 ppm = 3.0 mg solute / kg solution Which of the following are correct equivalent values ?

Explanation / Answer

ppm = (mass of solute in mg)/(mass of solution in kg or litreassuming they have same density of water) a) is wrong: it should be 0.05ppm b) is correct c) is correct d) is correct e) is correct Hope this helps!
