What is a solution called when it contains as much solute as it can possibly hold at a given temperature?

Saturated solution.

Explanation:

A saturated solution is a solution that contains as much solute (maximum solute) as the solvent can hold at a given temperature. Increase in temperature, or pressure might increase the solubility of more solute in the solution. Also the solubility of some solute in a given solvent depends on its chemical nature. It's a known fact that polar solutes dissolves or are soluble in polar solvents.

b) mutualism

hope this : )

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
