Question

calculate the number of molecules of sulphur S8 (s=32) present in 16 g of solid sulphur.​

Answer 1

Answer:

This means 256 g of solid sulphur contains = 6.022 x 1023 molecules. Therefore, 16 g of S8 contains 3.76 x 1022 molecules. Was this answer helpful?

Answer 2

Answer:

molar mass of sulphur i.e S8 molecule = 32 ×8 g

so 32 × 8 g of sulphur contain = 1 mole of molecules

so 16 g contains =( 1/32×8 ) × 16 moles

= 1/16 moles = 1/16 × 6.022 × 10^(23)

= 0.376375 × 10^(23)

= 3.76375 × 10^( 22) molecules of S8
