JEE MAIN - Chemistry (2016 - 9th April Morning Slot - No. 7)
An organic compound contains C, H and S. The minimum molecular weight of the
compound containing 8% sulphur is :
(atomic weight of S = 32 amu)
(atomic weight of S = 32 amu)
200 g mol$$-$$1
400 g mol$$-$$1
600 g molā1
300 g molā1
Explanation
We know that 8% sulphur means 8 g of sulphur present in 100 g of an organic compound.
Thus, 32 g of sulphur present in $${{100} \over 8} \times 32g$$ = 400 g of organic compound.
Therefore, minimum molecular weight of the compound is 400 g mol$$-$$1.
