Question

How many chloride ions are present in 1.7grams of magnesium chloride crystals?

Answer 1

mols MgCl2 = grams/molar mass = approx 0.02. There are 2 mols chloride ions per 1 mol MgCl2 so you have approx 0.04 mols Cl^-. There are 6.02E23 chloride ions in 1 mol so there must be ????? total chloride ions in 0.04 mols chloride ions.
I estimated the numbers; you should go through and recalculate all of the estimates.
