Given:
[tex]\text{mass}_{solute} = \text{20.0 mg = 0.0200 g}[/tex]
[tex]\text{mass}_{solution} = \text{50.0 g}[/tex]
Required:
concentration (in ppm)
Solution:
[tex]\text{concentration (in ppm)} = \frac{\text{mass}_{solute}}{\text{mass}_{solution}} × 10^{6}[/tex]
[tex]\text{concentration (in ppm)} = \frac{\text{0.0200 g}}{\text{50.0 g}} × 10^{6}[/tex]
[tex]\boxed{\text{concentration (in ppm) = 400. ppm}}[/tex]
