Recall the formula for density, which is defined as mass divided by volume: \(\text{Density} = \frac{\text{Mass}}{\text{Volume}}\).
Identify the given values: mass = 27 g and volume = 9 cm\(^3\).
Substitute the given values into the density formula: \(\text{Density} = \frac{27\ \text{g}}{9\ \text{cm}^3}\).
Perform the division to find the density value (do not calculate the final number here, just set up the expression).
Express the units of density as grams per cubic centimeter (g/cm\(^3\)) to complete the answer.
