The compound has sulphur=8%
∴
∴
8g of S is present in 100g
∴
∴
32g of S is present in

1008
×32=400g
×32=400g
[Least molecular mass means that at least one atom of sulphur should be present in molecule]

Explanation:
That is easy…
Atomic mass of Sulphur is 32 AMU
if 8% of the molecular mass is sulphur or 32 AMU
total molecular mass = 32x100/8 AMU = 400 AMU
