0.09 g/cm^3
B
275 g/cm^3
C
11 g/cm^3
D
5.5 g/cm^3

Verified step by step guidance1
Recall the formula for density, which is defined as mass divided by volume: \(\text{Density} = \frac{\text{Mass}}{\text{Volume}}\).
Identify the given values from the problem: mass = 55 g and volume = 5 cm\(^3\).
Substitute the given values into the density formula: \(\text{Density} = \frac{55\ \text{g}}{5\ \text{cm}^3}\).
Perform the division to find the density value (do not calculate the final number here, just set up the expression).
Express the units clearly as grams per cubic centimeter (g/cm\(^3\)), which is the standard unit for density in this context.
