The density of a substance is given by the formula:

$\text{Density} = \frac{\text{Mass of the substance}}{\text{Volume of the substance}}$

First, calculate the mass of the substance: $\text{Mass of the substance} = \text{Mass of graduated cylinder with substance} - \text{Mass of empty graduated cylinder}$ $\text{Mass of the substance} = 14.72 \, \text{g} - 12.55 \, \text{g} = 2.17 \, \text{g}$

Next, we know the volume of the substance is 7.06 mL.

Now, use the density formula: $\text{Density} = \frac{2.17 \, \text{g}}{7.06 \, \text{mL}} \approx 0.3073 \, \text{g/mL}$

The density of the substance is approximately 0.307 g/mL.
