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

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

  • A.
    196
  • B.
    49
  • C.
    106
  • D.
    82
Correct Answer: Option B
Explanation

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
