Explanation:
Calculate the number of molecules of sulphur (S8) present in 16 g of solid sulphur. ∴ 16 g of sulphur = 16 256 1 16 = moles = 0.125 moles 1 mole of S8 molecules = 6.023 × 1023 number of molecules ∴ 1 16 mole of S8 = 6.023 × 1023 number of molecules × 1 16 .

Answer:
gram atomic mass of sulphur-32g
32 g - 1mole
1g-1/32 mole
16g-1/32*16=1/2 mole
no of molecules in 1/2 mole =6.022*10^23/2=3.011*10^23
