How many atoms does argon have per cubic centimeter?

Answer 1

Argon is a gas, so it depends on temperature and pressure. At standard temperature and pressure, 1 mole of ideal gas takes up 22.4 liters, which is 22400 cubic centimeters. There are 6.023 x 10^23 atoms in 1 mole. So dividing gives 2.69 x 10^19 atoms per cm³ at standard temperature & pressure (1 atmosphere & 0° C)

Answer 2

The number of atoms per cubic centimeter of argon depends on the density of the argon gas or material. Pure gaseous argon at standard temperature and pressure (STP) has a density of 1.784 grams per liter, which is equivalent to approximately 2.920 x 10^19 atoms per cubic centimeter. However, the density of solid or liquid argon may be different, and it can vary based on temperature and pressure.
