Final answer:
The mass of the rock is 150 g.
Step-by-step explanation:
To find the mass of the rock, we can use the equation for density: d = m/v. In this equation, d represents density, m represents mass, and v represents volume. We are given the density (10 g/cm³) and volume (15 cm³) of the rock. Plugging these values into the equation, we get:
10 g/cm³ = m / 15 cm³
To solve for m (mass), we can rearrange the equation to m = d * v. Substituting the given values, we get:
m = 10 g/cm³ * 15 cm³
Simplifying the expression, we find that the mass of the rock is 150 g. Therefore, the correct answer is b) 150 g.
