How many moles of argon are in 4.80x10^24 atoms of argon

7.97 mol Ar

Explanation:

Use Avogadro's number to convert atoms to moles.  This number is the number of atoms in one mole.  There are 6.022 × 10²³ atoms in one mole.

Divide the number of atoms given by Avogadro's number.

(4.80 × 10²⁴)/(6.022 × 10²³) = 7.97 mol

There are 7.97 moles of argon.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
