Answer:

The number of atoms is 6.83 grams of potassium is
1.05* 10^(23) atoms.

Step-by-step explanation:

Mass of the potassium element = 6.83 g

Atomic mass of potassium = 39.10 g/mol

Moles of potassium =
(6.83 g)/(39.10 g/mol)=0.175 mol

According to mole concept :

1 mole =
N_A=6.022* 10^(23) atoms/ions/ molecules

Total number of atoms of potassium in 0.175 moles:


=0.175 * 6.022* 10^(23)  =1.05* 10^(23) atoms

So, number of atoms is 6.83 grams of potassium is
1.05* 10^(23) atoms.
