Your question does not make sense, an almost infinite amount of solution could be prepared if desired
%(v/v) = [(volume of solute)/(volume of solution)] x 100% 2% =[(volume of solute)/250 mL] x 100% 2%/100% = volume of solute/250 mL 0.02 x 250 mL = volume of solute 5 mL = volume of solute
the mass of a solute in a given volume of solution or mass/volume
They are both the same thing.
No. It refers to the relative volumes of solute to solvent, not the physical amount.
