Would you please help need asap The analysis of a compound gives the following percent composition by mass:
C: 56.70 percent; H: 8.419 percent; S: 11.65 percent; O: 23.24 percent. What is its molecular formula, given that its molar mass is 275.4 g?

C?H?S?O?
C atoms
H atoms
S atoms
O atoms

C atoms= 13

H atoms= 23

S atoms= 1

O atoms= 4

Explanation:

No. of C moles=

No. of H moles=

No.of S moles=

No.of O moles=

So the ratios are,

C : H : S : O

4.73 : 8.419 : 0.364 : 1.4525

13 : 23 : 1 : 4

So the empirical formula will be

To find the final answer

It approximately equals 1
