Answer:

density = 1.43 × 10⁻³ g/cm³

Step-by-step explanation:

We are told that oxygen gas of mass 2.23 kg has a volume of 1.56 × 10⁶ cm³, and we are told to find its density in g/cm³.

To do this we have to first convert the mass, which is given in kg, to g:

mass = 2.23 kg = 2.23 kg × 1000 [tex]\mathrm{_\frac{g}{kg}}[/tex]

                          = 2230 g

Next, we can find the density of the gas using the following formula:

[tex]\boxed{density = \frac{mass}{volume}}[/tex]

⇒ density = [tex]\mathrm{\frac{2230 \ g}{1.56 \times 10^{6} \ cm^3}}[/tex]

                 = 1.43 × 10⁻³ g/cm³

Therefore, the density of the oxygen gas is 1.43 × 10⁻³ g/cm³.
