If the molecular mass of tetraoxosulphate (VI) acid is 98, calculate its vapour density.

  • A 196
  • B 49
  • C 106
  • D 82

The correct answer is B. 49

Molecular mass = Vapour Density x 2

  Vapour Density = \(\frac{\text{Molecular Mass}}{2}\)

  Where Molecular mass = 98g/mol

  Vapour Density = \(\frac{98}{2}\)

  Vapour Density = 49g/mol
