)the solubility of mnso4 monohydrate in water at 20 °c is 70.0 g per 100.0 ml of water. a solution at 20 °c that is 4.22 m in mnso4 monohydrate is best described as a(n) solution. the formula weight of mnso4 monohydrate is 168.97 g/mol.

4.22 M monohydrate is best described as supersaturated solution

Explanation:

in a supersaturated solution, solution contains excess amount of solute than its normal capacity.

70.0 g of monohydrate = moles of monohydrate

(number of moles is the ratio of mass to molar mass)

So, solubitiy of monohydrate in terms of molarity = = 4.14 M

As the molarity of given solution in greater than normal solubility of monohydrate therefore the solution is best described as a supersaturated solution.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
