<u>Answer:</u> The moles of chloride ions in sodium chloride is moles, in magnesium chloride is moles and in aluminium chloride is moles
<u>Explanation:</u>
We are given:
Moles of sodium chloride in 1 L of solution = 0.10 moles
Moles of magnesium chloride in 1 L of solution = 0.10 moles
Moles of aluminium chloride in 1 L of solution = 0.10 moles
We need to calculate the moles of chloride ion in each solution in 1 mL of solution. The conversion factor used is:
1 L = 1000 mL
- <u>For sodium chloride:</u>
1 mole of NaCl produces 1 mole of sodium ions and 1 mole of chloride ions.
Moles of chloride ions in 1 L solution = 0.10 moles
Moles of chloride ions in 1 mL solution = moles
- <u>For magnesium chloride:</u>
1 mole of produces 1 mole of magnesium ions and 2 moles of chloride ions.
Moles of chloride ions in 1 L solution = (0.10 × 2) = 0.20 moles
Moles of chloride ions in 1 mL solution = moles
- <u>For aluminium chloride:</u>
1 mole of produces 1 mole of aluminium ions and 3 moles of chloride ions.
Moles of chloride ions in 1 L solution = (0.10 × 3) = 0.30 moles
Moles of chloride ions in 1 mL solution = moles
Hence, the moles of chloride ions in sodium chloride is moles, in magnesium chloride is moles and in aluminium chloride is moles
