Answer 1

An organic compound on analysis was found to contain 0.032% of sulphur by mass. the molecular mass of the compound, if its one molecule contains two sulphur atoms, is

Explanation:

The compound contains 0.032% of sulphur by mass.

We will let the molecular mass of compound be 'Y'.

Atomic mass of sulphur- 32g atomic mass of 2 sulphur atoms =(32∗2)g because 0.032% sulphur is present in the compound,

percentage of sulphur* total molecular weight of compound = weight of compound.

0.032% of y=32∗2 (0.032/100)∗y=64 y=(64∗100)/0.032 y=2 ∗ 10⁵g

The molecular weight of the compound is 2 ∗ 10⁵grams
