Question 23

The density of a gas can be calculated using the formula:

density=massvolume \text{density} = \frac{\text{mass}}{\text{volume}} density=volumemass​

An analyst carried out an experiment to determine the density of argon gas under specific laboratory conditions.

A glass gas density bulb was first completely evacuated of all air and its mass was measured. The bulb was then filled with pure argon gas and its mass was measured again.

Use the experimental results in Table 1 to calculate the density of the argon gas in g cm−3\text{g cm}^{-3}g cm−3.
