Which one of the following correctly represents the concentration ter…

$\text{ppm}=\frac{\text{Number of parts of the component}}{\text{Total number of parts of all the components of the solution}}$

$\text{ppm}=\frac{\text{Number of parts of the component}}{\text{Total number of parts of all the components of the solution}}×10^{12}$

$\text{ppm}=\frac{\text{Number of parts of the component}}{\text{Total number of parts of all the components of the solution}}×10^{6}$

$\text{ppm}=\frac{\text{Number of parts of the component}}{\text{Total number of parts of all the components of the solution}}×10^{3}$
