Question

How many atoms are present in 2 mols of S8 molecules? How many atoms are present in 2 mols of S 8 molecules? How many atoms are present in 2 mols of S 8 molecules?

please provide proper steps with correct answer.

Answer 1

hey mate !!

Answer:

Molar mass of S8 = 32×8 = 256 g

so,

in one mole of S8 = 256 g of S8 = 6.022×10²³ molecules of S8 = 48.176×10²³ atoms of S

so,

in two moles of S8 = 48.176×10²³×2 = 96.352×10²³ = 9.6352×10²⁴ atoms of S
