The correct answer is 9.4897 mL
It is necessary to understand a substance's mass, volume, and density in order to answer this question. By dividing a material's mass by volume, the density of the substance may be calculated. The equation for density may now be written in mathematical form using the expression for density, and the equation for mass can be produced by rearrangement using the equation for density as a starting point.
Mass of acetone = 7.44 g (given)
Volume of acetone (v) = mass of acetone ÷ density of acetone
V = 7.44 g ÷ 0.784 g/mL
V = 9.4897 mL
Hence volume of acetone = 9.4897 mL
