No. of molecules in 32g(1 mole) of sulphur=6.022×10^23
No. molecules in 16 g of sulphur= x
x=(6.022×10^23×16)/32
x=(6.022×10^23)/2
x=3.011×10^23

Dear Student,
◆ Answer -
No of molecules = 3.011×10^23 molecules
● Explaination -
First we'll calculate no of moles in 16 g of sulphur.
No of moles = given mass / molecular mass
No of moles = 16 / 32
No of moles = 0.5 mol
No of molecules present in 16 of sulphur are -
No of molecules = No of moles × Avogadro's number
No of molecules = 0.5 × 6.022×10^23
No of molecules = 3.011×10^23 molecules
Therefore, 16 g of solid sulphur contain 3.011×10^23 molecules of sulphur.
Hope this helps you ...
