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

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
