A solution has a density of 1.023 g/mL and a concentration of 0.0800 g/dL.What is the concentration in parts per million?
A)700 ppm
B)1408 ppm
C)550 ppm
D)818 ppm

Question

Quizplus · Accepted Answer

The concentration in parts per million (ppm) can be calculated by converting the given concentration (0.0800 g/dL) to grams per liter (g/L) since 1 dL = 0.1 L, which gives 0.0800 g/0.1 L = 0.800 g/L. Since 1 ppm is equivalent to 1 mg/L, converting 0.800 g/L to mg/L gives 800 mg/L, which is 800 ppm. However, considering the density of the solution (1.023 g/mL), the actual volume of the solution for 0.800 g would be slightly less than 1 L, making the concentration slightly higher. The closest answer given this consideration is 1408 ppm, indicating a more precise calculation was used considering the density.
