Identify the formula for density, which is the mass of an object divided by its volume: \(\text{Density} = \frac{\text{Mass}}{\text{Volume}}\).
Note the given values: mass = 45.5 grams and volume = 2.4 cm\(^3\).
Substitute the given values into the density formula: \(\text{Density} = \frac{45.5\ \text{g}}{2.4\ \text{cm}^3}\).
Perform the division to calculate the density value (do not calculate the final number here, just set up the expression).
Express the density with the correct units, which will be grams per cubic centimeter (g/cm\(^3\)).
