Question

calculate the number of molecules of sulphur present in 16 g of solid sulphur.

Answer 1

MOLECULAR MASS OF SULPHUR IS 32GM

MEANS 1MOLE SULPHUR=32GM=6.022×10^23 MOLECULES . SO,

16GM SULPHUR=
0.5 MOLE=3.011×10^23MOLECULES



HOPE YOUR PROBLEM IS SOLVED

$<b>$☺ Hello mate__ ❤

◾◾here is your answer.

1 mole of solid sulphur (S8)

= 8 × 32g

= 256g

i.e., 256g of solid sulphur contains

= 6.022 × 10^23 molecules

Then, 16g of solid sulpur contains

(6.022×10^23 /256 )16 molecules

= 3.76 × 10^22 molecules (approx)
