Calculate the ppm of mercury in water in given sample contain
`40mg` of `Hg` in `600ml` of solution .

Explanation

To calculate the parts per million (ppm) of mercury in the given water sample, we can follow these steps:

### Step 1: Understand the formula for ppm
The formula for parts per million (ppm) is given by:

\[ \text{ppm} = \left( \frac{\text{mass of solute (mg)}}{\text{mass of solution (g)}} \right) \times 10^6 \]
