Question

What is the molar concentration of potassium ions in a 0. 250 m k2so4(aq) solution?

Answer 1

The molar concentration of potassium ions in a  0. 250 m K₂SO₄(aq) solution is 2.

What is molar concentration?

The molar concentration of a solution is the presence of solute in one unit of a solution.

Molar concentration = number of moles / volume

The volume is given 0.250 m

To calculate the number of moles:

There will be 2 moles of potassium and  1 mole of sulfate in one L of the solution.

So in 0.250 L

0.250 x 2 x 1 = 0.500

The total number of moles of potassium and sulfate ion are 0.500

Now, putting the value:

Molar concentration = number of moles / volume

0.500 / 0.250 = 2

Thus, the molar concentration is 2.
