Question

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

Answer 1

hey
gram atomic mass of sulphur-32g
32 g - 1mole
1g-1/32 mole
16g-1/32*16=1/2 mole
no of molecules in 1/2 mole =6.022*10^23/2=3.011*10^23
Hope this helps you

Answer 2

$<b>$☺ 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)
