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)782 ppm
C)800 ppm
D)818 ppm

To convert the concentration from g/dL to ppm, first convert g/dL to g/mL: 0.0800 g/dL = 0.000800 g/mL. Then, use the density to find the mass of the solution in 1 mL: 1.023 g/mL. The concentration in ppm is (0.000800 g/mL / 1.023 g/mL) * 1,000,000 = 782 ppm.
