○ a. 152 g/cm³
○ b. 950 g/cm³
○ c. 0.65 g/cm³
○ d. 1.52 g/cm³
□ mark for review (will be highlighted on the review page)

Explanation:

Step1: Recall density formula

The formula for density ($
ho$) is $
ho = \frac{m}{V}$, where $m$ is mass and $V$ is volume.

Step2: Substitute values

Given $m = 38$ grams and $V = 25\ \text{cm}^3$, substitute into the formula: $
ho = \frac{38}{25}$.

Step3: Calculate the result

$\frac{38}{25} = 1.52\ \text{g/cm}^3$.

Answer:

D. 1.52 g/cm³
