How many atoms are in a sample of 1.83 moles of potassium (K) atoms?
A) 3.04 × 10-24 atoms K
B) 3.29 × 1023 atoms K
C) 1.10 × 1024 atoms K
D) 6.02 × 1023 atoms K

Respuesta :

Avogadro's number represents the number of units in one mole of any substance. This has the value of 6.022 x 10^23 units / mole. This number can be used to convert the number of atoms or molecules into number of moles.

 
1.83 moles K (6.022 x 10^23 atoms / mole ) = 1.10 x 10^24 atoms K
