Question

Acompound poses 8% sulphur by mass the least molecular mass

Answer 1

Let the least molecular mass of the compound be 'M'

For the compound to have least molecular mass, it must contain only 1 sulphur atom in it.

Therefore, 8% of 'M' = 32
              
             (8 x M)/100  =  32

                             M = 3200/8

                             M = 400

Thus, the least molecular mass of the compound is 400
