Question

16g of s8 molecules contian _____
(a) 3.78×10^22 atoms
(b) 3.78×10^22×8 atoms
(c) 3.78×10^22 moles
(d) 3.78 ×10^23 molecules​

Answer 1

Answer:

3.76×20^22×8 atoms present in 16g of S8 molecules

Explanation:

256g of mass present in 6.022×10^23 molecules of a S8 molecule

Therefore, 16g ----------------------------------- 6.022×10^23 × 16 / 256

= 3.76 ×10^22 molecules

Then, 1 molecule of S8 present 8 atoms

so, 3.76A×10^22 molecules present -------- 3.76×10^22×8 atoms

Therefore, 8×3.76×10^22 atoms present in 16g of S8 molecule
