Question

sulphur molecule is know to be composed of 8 atom in a sample of 192 g of pure metwl calculate no of g atom and atom and moles and molecule​

Answer 1

Explanation:

Molecule of sulphur exist as S8,

Therefore mass of 1 mole of sulphur molecule is 256g

Hence number of molecules present in 256 g = 1 mole

Number of molecules present in 192 g = 256/ 192 mole

⇒ Number of molecules present in 192 g = 1.33 mole

Hence number of molecules present in 192 g = 1.33 × 6.022 × 1023 molecule.

= 8.029 × 1023 molecule.
