# Calculate the Number of Molecules of Sulphur (S8) Present in 16 G of Solid Sulphur. - Science

Calculate the number of molecules of sulphur (S8) present in 16 g of solid sulphur.

#### Solution

1 mole of solid sulphur (S8) = 8 × 32 g = 256 g

i.e., 256 g of solid sulphur contains = 6.022 × 1023 molecules

"Then, 16 g of solid sulphur contains "=(6.022xx10^(23))/256xx16" molecules"

= 3.76 × 1022 molecules (approx)
