As the sulphur present is 8% by mass and minimum weight of sulphur in the compound can be 32 gm.
It means 8% mass of the compound = 32 gm.
or the molecular mass =32/8*100
= 400 gm.

A compound contains 8% sulphur. The minimum molecular weight of the co...
**Explanation:**
To determine the minimum molecular weight of the compound, we need to consider the atomic weight of sulphur.
The atomic weight of sulphur is approximately 32 g/mol.
We know that the compound contains 8% sulphur. This means that in 100 g of the compound, there will be 8 g of sulphur.
Now, to find the minimum molecular weight, we need to find the number of moles of sulphur in 8 g.
Number of moles = mass / molar mass
Number of moles of sulphur = 8 g / 32 g/mol = 0.25 mol
Since the compound contains only sulphur, the molecular weight of the compound is equal to the molar mass of sulphur.
Molecular weight of the compound = molar mass of sulphur = 32 g/mol
Since the molecular weight of the compound is 32 g/mol, it is less than all the options provided (a) 100, (b) 200, (c) 300, and (d) 450.
Therefore, the correct answer is option (d) 450.

How can it be 450. it should 400
