A compound possesses 8% sulphur by mass. The least molecular mass is

A

32

B

64

C

128

D

400

Text Solution

Verified by Experts

The correct Answer is:
D
Since sulphur is 8% by mass
`therefore` 8g sulphur is present in mass of 100 g or 32 g sulphur will be present in mass of =`100/8xx32=400`
Thus, if a minimum of one sulphur atom is present in the molecule, its minimum mass should be 400 amu.
