Final answer:
The number of gas particles in 1 cm³ of space varies depending on the conditions and location, but at standard temperature and pressure, there would be approximately 2.68 × 10¹⁹ gas molecules.
Step-by-step explanation:
The number of gas particles you would find in 1 cm3 of space varies depending on the conditions and location. However, on average, at standard temperature and pressure (STP), there would be approximately 2.68 × 1019 gas molecules in 1 cm3. This number is the same for all types or mixtures of gases.
