Question

Calculate the number of molecules of sulphur present in 64g of solid sulphur.
calculate the number of atoms present in it too.
[Avogadro Number = 6.022X10^23]
atoms mass of s =32u​

Answer 1

Answer:

2×6.022×10^23 or 2N_A

Explanation:

Moles = 64/32 = 2

Molecules = Moles×Avogadro Number = 2×6.022×10^23 or 2N_A
