Question

Calculate the number of atoms present in the 0.2 mole molecules of oxygen.​

Answer 1

Answer:

2.4088 × 10²³ atoms

Explanation:

oxygen molecule = O₂ ( 2 oxygen atoms)

no of atoms in 1 mole = 6.022 × 10²³

number of atoms in 0.2 mole molecules of oxygen.​

= 0.2 × 6.022 × 10²³ × 2

= 0.4 × 6.022 × 10²³

= 2.4088 × 10²³ atoms

Answer 2

Answer:

Explanation:

n=N/N₀

0.2=N/6.022×10²³

N=1.2044×10²⁴
