Find the molarity of the following solution: 734 grams of lithium sulfate (Li2SO4) is dissolved to make 2.5 liters of solution.

The molarity of the solution is 2.672

Explanation:

Molarity (M) is a way of expressing the concentration of solutions. It is defined as the number of moles of solute per volume of solution. The Molarity of a solution is determined by the following expression:

Molarity is expressed in units .

Being the molar mass of Li₂SO₄ 109.94 g/mol, then you can apply the following rule of three: if 109.94 grams are present in 1 mole, 734 grams will be present in how many moles?

amount of moles= 6.68 moles

Then:

Replacing in the definition of molarity:

and solving you get:

Molarity= 2.672

The molarity of the solution is 2.672
