Will 1 L of 1 M NaCl contain more chloride ions than 0.5 L of 1 M MgCl2 explain.

One liter of 1 M NaCl contains________ mole(s) of NaCl, therefore_______ mole(s) of chloride ions.

0.5 L of 1 M MgCl2 contains__________ mole(s) of MgCl2, therefore_________ mole(s) of chloride ions.

1 answer

mols NaCl in 1L of 1M = M x L = 1
mols Cl^- = 1 since there is 1 Cl ion in 1 mol NaCl.

0.5L of 1 M MgCl2 contains mols = M x L = 0.5 x 1 = 0.5 mols MgCl2.'
mols Cl^- will be twice that (2*0.5 = 1) = 1 mol Cl ions.
