10g of MgF2 are dissolved in 2.2L of water. What is the molarity of this solution?

Given :

10g of MgF₂ are dissolved in 2.2L of water.

To Find :

The molarity of this solution.

Solution :

Molar mass of MgF₂ is :

M = 24 + 19 + 19 g/mol

M = 62 g/mol

Moles in 10 g of MgF₂, n = 10/62 = 0.161 moles.

Now, we know molarity is given by :

Therefore, the molarity of solution is 0.073 M.

explanation:

shield volcanos are angry and get mad over the smallest things so much that there heads erupt   pahoehoe and a'a lava. a composite volcano is the poller opposite of a shield volcano. its   peaceful thing and knows how to control its emotions.
