Question

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

Answer 1

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.
