Here we are given the mass of both the solute (acetic acid) and solvent (water) so we can easily get the wt/wt % or also called mass %. Remember that this is the mass of solute over the mass of solution times a hundred so we still have to find the mass of the solution. We can easily get the mass of the solution by adding the masses of the solute and solvent.
