Question

Elemental composition of butyric acid was found to be 52.4 % C, 9.2%
H and 36.6 % 0. Determine its empirical formula.​

Answer 1

Answer:

C2H4O

Explanation:

• divide the percentage with atomic weight

52.4/12=4.366

9.2/1=9.2

36.6/16=2.287

• now divide this with least number I.e. 2.287 to simplify the ratio to find the empirical formula
• 4.366/2.287=1.9(C)
• 9.2/2.287=4(H)
• 2.287/2.287=1(O)
• empirical formula is C2H4O
