I think answer is 78 gm

#### Explanation:

% sum of all the elements = 100

% of H = 7.7

% left of remaining elements = 100-7.7 = 92.3%

now we find the % of other elements with help of ratio given

% of C =

% of O =

% of S =

now to finding empirical formula, we divide % by the atomic masses of respective element

C

O

S

H

now we divide all these %-mass ratio by the smallest %-mass ratio i.e. 1.28

C

S

O

H

so the empirical formula is
