Question

If there is one million mg2+ ions in mgcl2 how many chloride ions are there

Answer 1

As One Mg carries +2 Charge and Each Mg has 2 Cl ions.

So 1 million Mg = 2 million Cl ions

Answer 2

There are $2\times 10^6$ ions of chloride ions.

Explanation:

Number of magnesium ions = N = $10^6 ions$

1 molecule of magnesium chloride has 1 magnesium ion.

Molecules of magnesium chloriode will be

$1\times 10^6 molecules = 10^6 molecules[$.

1 molecule of magnesium chloride has 2 chloride ion. Then $10^6$ molecules of magnesium chloride will have:

$2\times 10^6 ions=2\times 10^6$ chloride ions.

There are $2\times 10^6$ ions of chloride ions.
