Question

Calculate the number of atoms present in 6g of Sulphur (S8)

Answer 1

Answer:

No. Of atoms= given mass/molar mass*avogadro no.

= 6g/32g*6.022*10^23

=1129125e23

Answer 2

Answer:

No.of moles = Given mass/Molecular mass

Given mass = 6g

Mass of sulfur =  32.065 u

Therefore, no.of moles = 6/32.065

No.of moles = 0.18711991267 moles

Therefore, no.of sulfur atoms = 0.18711991267 x 6.022 x 10²³(Avogadro's constant)

No.of sulfur atoms = 1.1268361141 x 10²³ atoms
