question
carbon dioxide has a density of 2.0 $\frac{g}{l}$. what mass will a 3.5 l sample of carbon dioxide have?
select the correct answer below:
7.0 g
0.57 g
1.8 g
1.1 g

Explanation:

Step1: Recall density formula

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

Step2: Substitute values

Given $
ho = 2.0\frac{g}{L}$ and $V=3.5L$. Then $m=2.0\frac{g}{L}\times3.5L$.

Step3: Calculate mass

$m = 7.0g$

Answer:

7.0 g
