Answer:

95.2 g/mol

Explanation:

To calculate the molar mass of MgCl2

We have to separately see the molar masses of Magnesium and Chlorine

Molar mass of Magnesium: 24.305 g/mol

Molar mass of Chlorine: 35.453 g/mol

As there are two atoms of chlorine in the said molecule so the molar mass of chlorine will be multiplied by 2.

35.453*2 = 70.906 g/mol

So the total molar mass of the said molecule = Molar mass of Mg + Molar mass of two atoms of chlorine

= 24.305 + 70.906

=95.211 g/mol

Rounding off to .1

95.2 g/mol

Suppose you have a mixture of solid mg(oh)2 and baso4, how do you separate the mixture

Step2247 [10]

This separation technique is a 4-step procedure. First, add H₂SO₄ to the solution. Because of common ion effect, BaSO₄ will not react, only Mg(OH)₂.

Mg(OH)₂ + H₂SO₄ → MgSO₄ + 2 H₂O

The aqueous solution will now contain MgSO₄ and BaSO₄. Unlike BaSO₄, MgSO₄ is soluble in water. So, you filter out the solution. You can set aside the BaSO₄ on the filter paper. To retrieve Mg(OH)₂, add NaOH.

MgSO₄ + 2 NaOH = Mg(OH)₂ + Na₂SO₄

Na₂SO₄ is soluble in water, while Mg(OH)₂ is not. Filter this solution again. The Mg(OH)₂ is retrieved in solid form on the filter paper.
