Question

1. find the mass of an object that has a density of 1.5 g/cm³ and has a volume of 8 cm³.

Explanation:

Step1: Recall the density formula

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

Step2: Substitute the given values

We know $
ho = 1.5\ \text{g/cm}^3$ and $V = 8\ \text{cm}^3$. Substitute these into the formula: $m = 1.5\ \text{g/cm}^3\times8\ \text{cm}^3$.

Step3: Calculate the mass

Multiply $1.5$ by $8$: $1.5\times8 = 12$.

Answer:

The mass of the object is $12$ grams.
