Question

calculate the number of molecules of sulphur present in 16 gram of solid Sulphur S8​

Answer 1

$\mathfrak{\huge{\green{\underline{\underline{ANSWER :}}}}}$

1 mole of solid sulphur (S8) = 8 × 32g = 256g

i.e., 256g of solid sulphur contains = 6.022 × 1023 molecules

Then, 16g of solid sulpur contains 6.022×1023 /256 × 16 molecules = 3.76 × 1022 molecules (approx)

Hope it will help you.
