how many chloride ions are in o.35 mol MgCl2?

To find the number of chloride ions in 0.35 mol of MgCl2, we first need to determine the number of moles of chloride ions present in 1 mol of MgCl2.

MgCl2 consists of one magnesium ion (Mg2+) and two chloride ions (2Cl-). This means that for every 1 mole of MgCl2, we have 2 moles of chloride ions.

Given that we have 0.35 mol of MgCl2, we can multiply this value by the ratio of chloride ions to MgCl2:

0.35 mol MgCl2 * 2 mol Cl- / 1 mol MgCl2 = 0.7 mol Cl-

Therefore, there are 0.7 moles of chloride ions in 0.35 mol of MgCl2.
