[K₂SO₄] = 2.50 M

Explanation:

We define the moles of solute: 6.01 mol of K₂SO₄

We define the solution's volume: 2.40L

To find out molarity we can make this rule of three:

In 2.40L of solution we have 6.01 moles of sulfate

Then, in 1L we have (6.01. 1) / 2.4 = 2.50 M

Molarity is a sort of concentration that indicates the moles of solute in 1L of solution
