Answer:

3.76 x 1022 molecules.

Explanation:

The molecular mass of the sulphur molecule is 32 × 8 = 256 u.

1 mole of sulphur molecules is equal to 256 grams.

This means 256 g of solid sulphur contains = 6.022 x 1023 molecules.

Then, 16 g of solid sulphur contains =6.022 x 1023 / 256 = 16 molecules

= 3.76375 x 1022 molecules

Therefore, 16 g of S8 contains 3.76 x 1022 molecules.

Answer:

3.76×1022 molecules

Explanation:

molecular mass of sulphur = 32×8

16 g of sulphur cointains 6.022 ×1022 molecules
