Question

How many number of atoms of sulphur are present in 0.2 moles of S8 molecule

Answer 1

$\clubsuit$  One Mole of S₈ Molecules Contain : 6.023 × 10²³ Molecules of S₈

⇒ 0.2 Moles of S₈ Molecules Contain : 0.2 × 6.023 × 10²³ Molecules of S₈

⇒ 0.2 Moles of S₈ Molecules Contain : 1.2046 × 10²³ Molecules of S₈

$\clubsuit$  Each S₈ Molecule Contains 8 Atoms of Sulphur

⇒ 1.2046 × 10²³ Molecules of S₈ Contain : 8 × 1.2046 × 10²³ Atoms of Sulphur

⇒ 1.2046 × 10²³ Molecules of S₈ Contain : 9.6368 × 10²³ Atoms of Sulphur

⇒ 0.2 Moles of S₈ Molecules Contain 9.6368 × 10²³ Atoms of Sulphur

Answer 2

Answer:

$\huge\underline\bold\red{ANSWER}$

Answer. Since 1 mole of S8 = 6.023* 10^23 molecules. = 9.63*10^23 atoms. Hence C is correct answer.
