The molar concentration of potassium ions in a 0. 250 m K₂SO₄(aq) solution is 2.
<h3>What is molar concentration?</h3>
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.
