D (solute) = 1,15 g/mL.

m (solute) = 45,95 g.

V (solute) = m (solute) : d (solute).

V (solute) = 45,95 g : 1,15 g/mL.

V (solute) = 39,95 mL.

V (solution) = V (solute) + V (solvent).

V (solution) = 39,95 mL + 250 mL.

V (solution) = 289,95 mL.

v/v = V (solute) : V (solution) · 100%.

v/v = 39,95 mL : 289,95 mL · 100%.

v/v = 13,77 %.
