Question

A compound possess 8% sulphur by mass the least molecular mass is
1.200
2.400
3.155
4.355​

Answer 1

The percentage ofSulphur in the compoundis=8%. The compound in question should contain at least 1-Sulphur atom. The Atomic Mass ofSulphur is 32. (It is 4 times the % of it) If thecompound contains 1 atom of Sulphur with the % Mass of 8%, theminimum Molecular Mass should be 100 x 4 = 400.

SO ANSWER IS

" 2. => 400"
