Question

Given that Avogadro's number is 6.02 x 10²³ particles (atoms, molecules, etc) per mole. How many atoms are there in 0.500 mole of zinc?

A. 1.20 x 10²⁴ atoms
B. 0.500 x 10²³ atoms
C. 131 atoms
D. 3.01 x 10²³ atoms

Answer 1

To find the number of atoms in 0.500 mole of zinc, you multiply the number of moles by Avogadro's number. The result is 3.01 × 10²³ atoms, which corresponds to option D.

Step-by-step explanation:

The question asks how many atoms are in 0.500 mole of zinc. Given that Avogadro's number is 6.02 × 10²³ particles per mole, we can calculate the number of atoms in 0.500 mole by simply multiplying the number of moles by Avogadro's number:
0.500 mole × 6.02 × 10²³ atoms/mole = 3.01 × 10²³ atoms

Therefore, there are 3.01 × 10²³ atoms in 0.500 mole of zinc, which corresponds to option D of the provided choices.
