Question

How to calculate the number of s8 molecules in 16 g of solid sulphur?

Answer 1

1 mole = 6.023×10^23 molecules
and we know that 32g of sulphur contain 1 mole particles
but in this case there are 8 atoms of sulphur in one molecule,
so, 32×8=256g

1 mole of sulphur molecules =256g
x =16g
by cross multiplication
x(256)=16
x=16/256
x=6.25×10^-2 molecules.

$<b>$☺ 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)
