Answer:

Well clearly it contains 90% water BY MASS.

Explanation:

Percentage solutions are normally quoted,

#"mass of component"/"mass of solution"xx100%#,

where #"mass of solution "=" mass of solute + mass of water."# This is also known as a mass fraction.. Beaker A was thus prepared by taking #10*g# of salt, and adding #90*g# of water. The volume of the solution would thus not be much different from #90*mL#.
