Answer: there are 1.2044 x 10²⁴ atoms present in 2 moles of argon gas.
Step-by-step explanation:
To determine the number of atoms present in a given number of moles of a substance, you can use Avogadro's number. Avogadro's number is approximately 6.022 x 10^23 atoms per mole.
Given that you have 2 moles of argon gas, you can calculate the number of atoms as follows:
Number of atoms = Number of moles * Avogadro's number
Number of atoms = 2 moles * 6.022 x 10^23 atoms/mol
Number of atoms = 1.2044 x 10²⁴ atoms
