Question

question 2
at standard temperature and pressure, carbon dioxide has a density of 1.98 kg/m³. what volume does 1.70 kg of carbon dioxide occupy at standard temperature and pressure?
○ 0.43 m³
○ 0.86 m³
○ 1.7 m³
○ 2.3 m³

Explanation:

Step1: Recall density formula

Density $
ho = \frac{\text{mass } m}{\text{volume } V}$, so $V = \frac{m}{
ho}$.

Step2: Plug in values

$m = 1.70\ \text{kg}$, $
ho = 1.98\ \text{kg/m}^3$.
$V = \frac{1.70}{1.98} \approx 0.86\ \text{m}^3$.

Answer:

B. 0.86 m³
