Which one of the following correctly represents the concentration term 'ppm'? |
$\text{ppm}=\frac{\text{Number of parts of the component}}{\text{Total number of parts of all the components of the solution}}$ $\text{ppm}=\frac{\text{Number of parts of the component}}{\text{Total number of parts of all the components of the solution}}×10^{12}$ $\text{ppm}=\frac{\text{Number of parts of the component}}{\text{Total number of parts of all the components of the solution}}×10^{6}$ $\text{ppm}=\frac{\text{Number of parts of the component}}{\text{Total number of parts of all the components of the solution}}×10^{3}$ |
$\text{ppm}=\frac{\text{Number of parts of the component}}{\text{Total number of parts of all the components of the solution}}×10^{6}$ |
The correct answer is Option (3) → $\text{ppm}=\frac{\text{Number of parts of the component}}{\text{Total number of parts of all the components of the solution}}×10^{6}$ The term ppm (parts per million) is defined as: $\text{ppm} = \frac{\text{Number of parts of the component}}{\text{Total number of parts of all components}} \times 10^6$
