)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.

yes it is balanced

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
