Question

16 g of S8molecules contain
(a) 3.78 x 104 atoms
(6) 3.78 x 1022 x 8 atoms
(c) 3.78 x 1022 moles
(d) 3.78 x 10molecules​

Answer 1

Answer:

a will be right option

mark as brilliant answer

Answer 2

no of moles=mass/molecular weight

no of moles=16/32*8

no of moles=1/16

no of molecules=no of moles*avagadro no

no of molecules=(1/16)*6.022*10²³

=0.378*10²³

=3.78*10²² molecules (approx)
