Density is mass per unit of volume. The density of argon is 1.778 × 10⁻³ gm/cm³.

Suppose that a finite amount of substance is there having its properties as:

Then, they are related as:

d = m/v

The volume of the tube = π × r² × h

                                = π × (2cm)² × 27.75 cm

                                = 348.716 cm³

Mass of Argon = Mass when tube is filled - Mass when tube is empty

                        = 188.87 g - 188.25 g

                        = 0.62 g

Now, the density of the gas can be written as,

Density = Mass / Volume

            = 0.62g / 348.716 cm³

            = 1.778 × 10⁻³ gm/cm³

Hence, the density of argon is 1.778 × 10⁻³ gm/cm³.
