Given :

Mass of given magnesium chloride, m = 256 g.

To Find :

How many grams of chloride are there in 256 g of magnesium chloride.

Solution :

Molecular formula of magnesium chloride is
MgCl_2.

Molecular formula of
MgCl_2 is, M = 95.211 g/mol .

Mass of chlorine in 1 mol of
MgCl_2 is , m = 35.5 × 2 = 71 g.

So, amount of chlorine in 256 gram
MgCl_2 :


m =(71* 256)/(95.211)\\\\m = 190.90\ g

Hence, this is the required solution.
