Answer :
Final answer:
To calculate the number of chloride ions in 9.5 grams of magnesium chloride, divide the mass by the molar mass of magnesium chloride.
Total number of chloride ions = 0.1 mol x 2 ions/mol = 0.2 ions
Explanation:
To calculate the number of chloride ions in 9.5 grams of magnesium chloride, we first need to determine the number of moles of magnesium chloride. We can do this by dividing the mass by the molar mass of magnesium chloride:
Molar mass of MgCl2 = 24 g/mol + (35.5 g/mol x 2) = 95 g/mol
Number of moles of MgCl2 = 9.5 g / 95 g/mol = 0.1 mol
Since each molecule of magnesium chloride contains 2 chloride ions, the total number of chloride ions in 9.5 grams of magnesium chloride is:
Total number of chloride ions = 0.1 mol x 2 ions/mol = 0.2 ions
