Determine the concentration of nitrate ions in 0.500 cm3 of 0.600 mol dm–3 of Fe(NO3)3 solution.

Sure, here are the steps to determine the concentration of nitrate ions in the given solution:

1. First, we need to understand the formula of the compound. Fe(NO3)3 means there are 3 nitrate ions (NO3-) for every 1 iron ion (Fe).

2. The given concentration of Fe(NO3)3 is 0.600 mol/dm3. Since there are 3 nitrate ions for every molecule of Fe(NO3)3, the concentration of nitrate ions is 3 times the concentration of Fe(NO3)3.

3. Therefore, the concentration of nitrate ions is 3 * 0.600 mol/dm3 = 1.800 mol/dm3.

4. However, the question asks for the concentration in a 0.500 cm3 solution. We need to convert this volume to dm3 because our concentration is in mol/dm3.

5. There are 1000 cm3 in 1 dm3, so 0.500 cm3 = 0.000500 dm3.

6. Finally, we can find the amount of nitrate ions in this volume by multiplying the concentration by the volume: 1.800 mol/dm3 * 0.000500 dm3 = 0.000900 mol.

So, the concentration of nitrate ions in 0.500 cm3 of the solution is 0.000900 mol.
