Question

Calculate the number of molecules of sulphur present in 16g of solid sulphur

please answer this question​

Answer 1

Explanation:

Hey Girl, Here You Go:

1 mole of solid sulphur (S8) = 8 x 32 g = 256 gi.e., 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

Another method

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 .

Stay safe and have a great Saturday.
