answer the following multiple choice questions about the reading.

1. a block of wood has a volume of 150 cm³ and a density of 0.8 g/cm³. what is the mass of the block?

a. 0.0053 g
b. 150.8 g
c. 120 g
d. 187.5 g

Explanation:

Step1: Recall density formula

The formula for density is $
ho = \frac{m}{V}$, where $
ho$ is density, $m$ is mass, and $V$ is volume. We need to solve for mass, so rearrange the formula to $m =
ho \times V$.

Step2: Substitute values

Given $
ho = 0.8\ \text{g/cm}^3$ and $V = 150\ \text{cm}^3$. Substitute into the formula: $m = 0.8 \times 150$.

Step3: Calculate the product

$0.8 \times 150 = 120$. So the mass of the block is $120\ \text{g}$.

Answer:

C. 120 g
