255 mL

Work Step by Step

If the solution contains 125 g sulfuric acid, and this is 38.08% of the solution by mass, the total mass of solution is $\frac{125}{0.3808} = 328$ g. We are also given the density of the solution as 1.285 g/cm$^{3}$, or 1.285 g/mL. The volume of the solution is therefore $328 g \times \frac{1 mL}{1.285 g}=255$ mL. We report the answer to three significant figures, because that is the fewest that any figure in the problem had (we only multiplied/divided).
