How many moles of ions are released when 0.27 mol of cobalt(ii) chloride, cocl2, is dissolved in water? 0.54 mol 0.18 mol 0.81 mol 0.27 mol?

- 0.81 moles of ions.

Solution:- The dissociation equation for the given compound is as follows...

From this, 1 mol of cobalt(II)chloride gives 1 mol of cobalt ion and 2 moles of chloride ion. So, 1 mol of the compound gives total 3 moles of the ions.

Now, we can calculate the moles of ions produced by 0.27 moles of the compound as...

0.27 mol of compound x (3 moles of ions/1 mol of compound) = 0.81 moles of ions

50.23 i believe is correct but don't quote me on that.
