Final answer:
To find the molar concentration of a pollutant in a lake, you can use the volume of water and the mass of the pollutant. Calculate the moles of solute by multiplying the volume of water by the concentration of the solute in ppm, then divide the moles by the volume to find the molar concentration.
Step-by-step explanation:
To find the molar concentration of a pollutant in a lake, you would need to know the volume of water in the lake and the mass of the pollutant in the lake. You can calculate the molarity of the pollutant using parts per million (ppm) as a ratio. Here is a stepwise pseudocode:
- Calculate the moles of solute by multiplying the volume of water (in liters) by the concentration of the solute (in ppm).
- Divide the moles of solute by the volume of water (in liters) to find the molar concentration of the pollutant.
For example, let's say the volume of water in the lake is 1000 L and the mass of the pollutant is 50 kg. You would first convert the mass to moles using the molar mass of the pollutant. Then, you would divide the moles by the volume of water to find the molar concentration.
