Question

i) Calculate the number of molecules of sulphur in in 16 gram of solid Sulphur (At. Mass of
Sulphur is 32u)
​

Answer 1

Answer:

We have to find the number of molecules present in 16g of solid sulphur.

We have to find the number of molecules present in 16g of solid sulphur.The molecular mass of the sulphur molecule is 32 × 8 = 256 u.

We have to find the number of molecules present in 16g of solid sulphur.The molecular mass of the sulphur molecule is 32 × 8 = 256 u.1 mole of sulphur molecules is equal to 256 grams.

We have to find the number of molecules present in 16g of solid sulphur.The molecular mass of the sulphur molecule is 32 × 8 = 256 u.1 mole of sulphur molecules is equal to 256 grams.This means 256 g of solid sulphur contains = 6.022 x 1023 molecules.
