Question

Calculate the number of moles present in 80g of sulphur, if the molecular formula is

S8.​

Answer 1

Explanation:

Therefore, the molecular mass of a molecule of sulphur that is S8 will be 32×8g = 256g. Therefore, we can write that the molar mass of solid sulphur is 256 g/mol. Number of moles of sulphur in 256g is 1 mol. Therefore, the number of moles of sulphur in 1 g will be 1256 mol.
