A one thousand liter sample of water contains one gram of iron (III) ions. What is the concentration of Fe3+(aq) in parts per million?
no
To determine the concentration of Fe3+(aq) in parts per million (ppm), we need to find the amount of Fe3+(aq) per liter of water and convert it to ppm. Here's how you can calculate it step by step:
1. Calculate the concentration of Fe3+(aq) in milligrams per liter (mg/L).
- Since the sample contains 1 gram of Fe3+(aq), which is equivalent to 1000 milligrams (mg), and the volume is 1000 liters, the concentration is 1000 mg / 1000 L = 1 mg/L.
2. Convert the concentration from milligrams per liter (mg/L) to parts per million (ppm).
- Since 1 mg/L is equivalent to 1 ppm, the concentration of Fe3+(aq) in ppm is also 1 ppm.
Therefore, the concentration of Fe3+(aq) in parts per million (ppm) is 1 ppm.
