Calculate the number of molecules of sulphur `(S_8)` present in 16g of solid sulphur.

Explanation

Mass of 1 mole of sulphur `(S_(8))=8xx32g`
256 g
`therefore` According to mole-concept,
number of molecules of sulphur `(S_(8))`
present in 256 g of solid sulphur = `6.022xx10^(23)`
`therefore` Number of molecules of sulphur `(S_(8))` present in 16g of solid sulphur = `(6.023xx10^(23))/256xx16=3.76xx10^(22)`
