The density of a gas can be found using the equation:
density=massvolume \text{density} = \frac{\text{mass}}{\text{volume}} density=volumemassA student carried out an experiment to find the density of carbon dioxide gas.
The mass of an evacuated stoppered flask (containing no gas) was measured. The flask was then completely filled with carbon dioxide gas and its mass was measured again.
Use the results in Table 1 to calculate the density of carbon dioxide gas in g cm−3\text{g cm}^{-3}g cm−3.
| Measurement | Value |
|---|---|
| Mass of stoppered flask (evacuated) | 122.145 g |
| Mass of stoppered flask full of carbon dioxide | 123.085 g |
| Volume of flask | 500.0 cm³ |
