What is the Molarity of the Sulfate ion in a 2M K2SO4 solution?

The Molarity of the sulphate ion in a 2M   solution is 2M

Explanation:

Molarity is defined as the number of moles of solute dissolved per liter of the solution.

where,

n= moles of solute

= volume of solution in ml

Now as 1 mole of gives = 1 mole of

2 moles of gives = moles of

Thus Molarity of the sulphate ion in a 2M solution is 2 M
