Identify the given quantities: mass of the solution (m) = 24.5 g, and density (\(\rho\)) = 0.768 g/mL.
Recall the relationship between density, mass, and volume: \(\rho = \frac{m}{V}\), where \(V\) is the volume in mL.
Rearrange the formula to solve for volume: \(V = \frac{m}{\rho}\).
Substitute the known values into the equation: \(V = \frac{24.5\ \text{g}}{0.768\ \text{g/mL}}\).
Perform the division to find the volume in mL (do not calculate the final value here, just set up the expression).
